TASMAN RESOURCE MANAGEMENT PLAN
PROPOSED CHANGE NO. 13
PROPOSED VARIATION NO. 66
Water Allocation Review
(Motueka Central Plains and Middle Motueka Zones, including
Dove and Abel Tasman Zones and Community Water Supplies)
December 2008
EXPLANATORY STATEMENT
This Explanatory Statement applies to both Proposed Change No. 13 and Proposed Variation
No. 66.
The Council has an on-going programme of water resource investigations and monitoring that
continually improves the level of knowledge about water resources and the pattern of use of
water.
MOTUEKA WATER RESOURCES
Council investigation into the nature of groundwater resources in the Central Plains Zone has
shown that the amount of water that can be sustainably extracted can be significantly increased.
The results of this investigation work show that the allocation limit, set somewhat conservatively
when the water management provisions of the Plan were notified in 2001, can be substantially
increased without adverse effects. The new allocation limit takes into account water demand in
zones of the Motueka Catchment above Woodmans Bend.
The updated groundwater/river model for the Motueka/Riwaka Plains confirms the current
allocation limit of 855 l/sec including the accounting for taking irrigation water for all irrigable
land in the Central Plains. The model then predicts that the additional amount of water (283 l/sec)
could be taken from near the river without causing triggers to be breached during the modelled
severe drought year (e.g. 2000/01). The increased allocation will be restricted to a proposed new
Central Plains Subzone.
DRAWDOWN EFFECTS OF NEW WATER TAKES.
The Council has identified that it intends to protect minimum water supply needs of domestic and
stock water users, although it qualifies this protection by an exception that the bore fully
penetrates the alluvial aquifer.
An aquifer can be of variable thickness or depth, can be confined by impermeable layers or
unconfined. The majority of alluvial aquifers in our region are leaky between layers. They are
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 1
neither truly confined nor unconfined. The Motueka Gravel Aquifer in hydrogeological terms is
one aquifer with three interlinked layers. Pumping at any one site will affect all three layers over
time. The aquifer extends to some 20 metres deep in the Central Plains part of Motueka.
Some households whose bores are likely to be impacted by lowered groundwater levels in the
proposed new subzone will have reticulated water supplied as part of the proposed new
reticulation scheme for Motueka. However, a very small number of households that are not
reticulated may face the possibility of reduced security of supply in summer from existing bores
when the water table levels drop more than they currently do. The frequency at which
householders will be affected by increasing drawdown will vary according to sensitivity to
drawdown at that location, efficiency of the existing bore and frequency and severity of drought.
Most of these shallow bores would probably already suffer from the effects of lowered water table
levels in summer.
Council acknowledges that while some domestic bores may experience lower water levels in some
summers, the benefits of an increased allocation limit to the District are very significant and should
not be forgone because some bores are inadequate.
An amendment is to be made to the Plan that will allow domestic bores to be constructed at closer
spacings. This allows sufficient protection for domestic bores and also allows for replacement
bores to be constructed if an existing bore is inadequate.
RESERVATIONS
The plan currently recognises the need to provide for irrigation of irrigable Maori Perpetual Lease
Land and for future community water supply.
The Council has amended the quantities reserved for specified purposes to reflect likely future
demand more accurately and to take into account changes in land ownership and residential
development since the plan was first notified in 2001.
ALLOCATION LIMITS – MIDDLE MOTUEKA
Separate allocation limits have been introduced for the Dove and Stanley Brook catchments. They
were previously considered part of the Upper Motueka Zone, however only the lower (Granite)
reach of the Dove River reliably contributes flow to the Motueka River in summer.
Allocation limits for both these zones reflect the summer dry nature of the catchments and the
security of supply is likely to be less than the stated objective. Proposed new water meter
requirements will help the Council and the water users to understand more about patterns of
water use and security of supply. Even though little is known about current levels of security,
water balance calculations indicate that a little more water could be taken from shallow gravels in
the Dove without adversely affecting existing water users.
ALLOCATION LIMITS – ABEL TASMAN
Allocation limits have now been included for some of the smaller coastal catchments near the Abel
Tasman National Park, including Marahau, Otuwhero and Holyoake rivers. Although the Council
does not have a good knowledge of the uses and values of those water bodies, it has introduced a
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 2
conservative provisional water allocation limit to help manage reservation of water for potential
future water needs of the community and to provide some guidance for potential water users.
The allocation limit may be reviewed if there is more information about the significance of uses
and values in those water bodies.
FROST PROTECTION
Other changes in the pattern of water use are occurring as a result of an increasing amount of
water being taken to protect susceptible crops from damaging effects of frost. Fruit blossom of
crops, especially kiwifruit, are prone to damage by frosts. Water is sprayed on the vines to
provide protection for the developing flowers and fruit in spring when kiwifruit are particularly
vulnerable. In autumn, maturing fruit may also need protection from frosts, although the leaf
canopy provides a degree of protection and reduces the need for frost protection.
Effects of taking water for frost protection may be different from the effects of irrigation. River
flows are usually higher during spring and autumn, but the aquatic habitat requirements are also
different. For example, the higher flow needs of spawning fish and sufficient flow through gravels
to protect incubating eggs are particularly important and they might be adversely affect by frost
protection takes. The Plan is amended to account for this water use and a minimum winter flow
is proposed for the Riwaka River.
EVALUATION OF ALTERNATIVES UNDER SECTION 32 OF THE RESOURCE MANAGEMENT ACT
Council has considered technical reports detailing the resource investigation findings. It has
considered the benefits and costs, and effectiveness, efficiency and appropriateness of these
amendments. Key Section 32 reference documents for Proposed Change No. 13 and Proposed

2.
CHAPTER 30: TAKING, USING, DAMMING AND DIVERTING WATER
2.1
SECTION 30.0: INTRODUCTION
2.1.1
In section 30.0A:
(a)
Replace under the heading ‘Motueka’ and in the second to last sentence of the first
paragraph with:
A high-yielding aquifer comprised of three interlinked layers underlies the central part of the
Motueka Plains.
(b)
2.1.2
Delete under the heading ‘Motueka’ and in the last paragraph, the word “draft” in
relation to the Motueka River Conservation Order.
In section 30.0D:
(a)
Insert under the heading ‘Water Abstraction’, the following two new paragraphs:
Other changes in the pattern of water use are occurring as a result of increasing amounts of
water being taken to protect susceptible crops from damaging effects of frost. Fruit blossom
of crops, especially kiwifruit, are prone to damage by late frosts. Water is sprayed on the
vines to provide protection for the developing fruit. In autumn, ripe fruit may also need
protection from frosts.
Effects of taking water for frost protection are different from effects arising from water takes
for irrigation during summer. While flows are usually higher during autumn and spring,
the aquatic habitat requirements are also different. For example, the higher flow needs of
spawning fish and sufficient flow through gravels to protect incubating eggs are particularly
important.
(b)
Under the heading ‘Gravel Extraction’, in the second paragraph:
(i)
Replace the word “Corner” with “Bend” and delete the word
“significantly” from the third sentence.
(ii)
Insert a new fourth sentence as follows:
Recent modeling shows that groundwater levels in the Motueka Plains aquifer
would be reduced by 0.1 metres if the bed levels in the lower Motueka River are
lowered by 0.3 metres.
(iii)
Add to the end of the last sentence:
and effects of the gravel extraction activities will be accounted for in Part IV (Part
IV is currently in preparation).
2.2
SECTION 30.1: REDUCED WATER BODY FLOWS OR LEVELS
2.2.1
Insert two new policies:
30.1.6A
To adopt a water allocation limit for the groundwater of the Motueka Plains aquifers
based on the sustainable yield of the aquifer that takes into account:
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 5
(a)
impact of groundwater abstraction on flows in the Motueka River;
(b)
potential adverse effects arising from seawater intrusion and the extent to which
they can be mitigated, including by providing alternative water supplies where
bores are affected by seawater intrusion, particularly in the coastal part of the Hau
Zone;
(c)
potential for inducing additional recharge to the aquifers from the Motueka River
by allowing greater rates of abstraction in the high yield area of the Central Plains
Zone;
(d)
irrigation needs of land in the Middle Motueka and Upper Motueka water
management zones;
(e)
desirable security of supply standards for abstractive water users;
and to review the allocation limit if further monitoring and investigation confirms that
the Hau Zone seawater intrusion trigger for rationing is not affected by water abstraction
in the adjacent zones.
30.1.6B
2.2.2
To ensure that water takes from the Central Plains Subzone avoid, remedy or mitigate
adverse drawdown effects on other water users and to:
(a)
require bore testing, including step drawdown and constant discharge tests to
assess localised drawdown and hydraulic characteristics; and
(b)
ensure effects of takes from any single bore or collection of bores in the same bore
field take into account well performance, yields, localised drawdown and long term
yield of existing fully penetrating bores.
Amend Policy 30.1.7(b) to:
any allocation limit for water takes for consumptive use for the water body;
2.2.3
Insert two new policies:
30.1.9B
Except for takes from the Riwaka River, when assessing a resource consent application to
take water for frost protection of crops, to take into account actual and potential adverse
effects of the take, either on its own or in combination with other similar water takes on:
(a)
aquatic habitat including habitat of fish and eels;
(b)
spawning and egg production of fish and eels;
(c)
effects on the natural flow variability of the river;
(d)
adverse effects on existing water users;
(e)
adverse drawdown effects on groundwater users;
and to require measures to ensure that water use is efficient and that the natural flow of
any river does not reduce below the Mean Annual Low Flow (MALF – 7 day).
30.1.9C
To avoid, remedy, or mitigate adverse effects of water takes from the Riwaka River for
frost protection by:
(a)
ensuring that the total instantaneous takes from the river do not reduce the
minimum flow for May – October below 615 litres per second;
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 6
2.2.4
assisting the Riwaka Water User Committee to ensure the minimum flow is
maintained;
(c)
requiring time stamped water metering for water takes used for frost protection;
(d)
carrying out resource investigation to understand more about the relationship
between water takes for frost protection on river flows;
(e)
limiting takes for frost protection to land within the Riwaka Water Management
Zone.
Amend Policy 30.1.13 by:
(a)
(b)
(c)
2.2.5
(b)
replacing the words “zones where allocation limits have been established for that
zone have been met or exceeded” with “the Moutere Surface Water and Wai-iti
zones”;
inserting after “application” the word “where” and deleting from the beginning of
(a) the word “if”.
inserting after ”assessed under Policy 30.1.9” the words “or in relation to the
security of supply for other existing water users”.
In 30.1.50 (Principal Reasons and Explanation):
(a)
Insert under the heading ‘Groundwater’, the following new paragraphs:
In assessing the drawdown effects on other bores in alluvial aquifers such as those in the
Motueka or Waimea Plains, a fully penetrating bore is drilled to the bottom of the aquifer
and constructed in such a way that water is abstracted from the deepest part of the bore in
order to maximise water quality and water quantity. If bores are not fully penetrating, they
may be adversely affected by pumping drawdown effects from other bores.
Allocation limits for the Motueka Plains aquifers are based on the sustainable recharge of the
aquifer and take into account interaction with the Motueka River flows and irrigation needs
in the upper catchment. The limits for the Central Plains Zone also recognise a high yield
area of the aquifer near to the River, where higher rates of groundwater abstraction can be
sustainably provided for.
The allocation limits currently reflect the potential adverse affects of seawater intrusion in
the Hau Zone. However, it is possible that seawater intrusion is a localised effect mainly in
the coastal margin of the Hau Zone and is not a relevant trigger for groundwater takes in
the Central Plains Zone. Until Council has gathered more data and monitored the effects of
this allocation regime, it will adopt a conservative allocation limit for the Central Plains
Zone that accounts for possible seawater intrusion effect in the Hau Plains Zone. Better
understanding about interactions between the Hau Plains and Central Plains zones and the
potential for mitigation of seawater intrusion in the Hau Plains Zone (as is currently carried
out by the Lower Moutere Water Scheme) may mean Council can further review allocation
limits for the Central Plains Zone in the future.
(b)
Insert under the heading ‘Water Allocation’, the following new paragraph:
Water is increasingly being taken for frost protection of susceptible crops to avoid damage to
blossom and also to protect fruit from damage from autumn frost. The cumulative effects of
water takes for frost protection are significant in the Riwaka River and may develop for other
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 7
water bodies. A minimum flow will protect the Riwaka River and potential adverse effects
will be avoided for other rivers by taking into account the cumulative impacts of frost
protection takes on the river’s flow variability and on its Mean Annual Low Flow.
Drawdown effects of groundwater takes, as well as effects on connected surface water bodies,
will also be accounted for when assessing groundwater takes for frost fighting.
2.3
SECTION 30.2: ALLOCATION OF FRESH WATER BETWEEN COMPETING WATER USERS
2.3.1
Insert a new clause into Policy 30.2.11 (concerning water meters):
(e)
2.3.2
to require efficient use of water
Insert at the end of Policy 30.2.14 (concerning security of supply):
and to adopt a higher security of supply where knowledge about cumulative effects of water
abstraction on water bodies is not complete or where demand for water resources is lower.
2.3.3
In section 30.2.30 (Principal Reasons and Explanation):
(a)
Insert at the end of the first paragraph:
In assessing the drawdown effects on other bores in alluvial aquifers such as those in the
Motueka or Waimea Plains, a fully penetrating bore is drilled to the bottom of the aquifer
and the bore is constructed in such a way that water is abstracted from the deepest part of
the bore in order to maximise water quality and water quantity.
Domestic bores in the unreticulated areas of the Motueka Plains may be affected by
drawdown effects from neighbouring irrigation bores if the domestic bore is too shallow and
increasing allocation limits in the Central Plains Zone may impact on these bores. Council
intends to provide a reliable and secure community water supply to Motueka as an
alternative for domestic users. However, Council acknowledges that while some domestic
bores may experience lower water levels in some summers, the benefits of an increased
allocation limit to the District are very significant and should not be forgone because some
bores are inadequate.
(b)
Insert in the 6th paragraph after the words “lease arrangement to require water
permits” the words “for irrigation of irrigable land”.
(c)
Delete the ninth paragraph of section 30.2.30 commencing “Council may also apply
this rationing differential …”
(d)
Insert the word “minimum” before the words “security of supply” in the second
sentence of the 16th paragraph commencing, “In setting allocation limits … “.
(e)
Insert two new paragraphs after the 16th paragraph:
Some Water Management Zones have allocation regimes where the security of supply is
higher than the stated minimum. This may be because there is still uncertainty about the
exact nature of the water resource and recharge mechanisms and a more precautionary
approach has been used. The consequences of unsustainable extraction are significant and
irreversible damage to aquifers can be caused by over abstraction. Higher security of supply
is provided in the Moutere Groundwater Zones and in the Central Plains and King
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 8
Edwards zones. Water users in these zones enjoy a relatively high security of supply as
triggers for rationing are set at levels that are unlikely to be triggered in a ‘1 in 10 year’
drought.
More data and improved understanding about the connections between the Hau Plains Zone
seawater intrusion risks and water takes in the Central Plains may allow Council to review
allocation limits while still providing for a security of supply that is consistent with stated
objectives.
(f)
Insert in the 18th paragraph after the first five words, i.e., “The Council will work
with”, the words “the Lower Moutere Water Scheme and other”.
(g)
Add to the end of the first sentence of the last paragraph the words “and in
accordance with the National Environment Standard for the measurement of water
takes”.

(e)
Delete the row: “TOTAL Upper Motueka Zone 1000”.
(f)
Insert in Note (1) [Figure 31.1F] and Note (2) [Figure 31.1E] after the words “litres

3.1.3
Delete condition (g) from 31.1.3 and the exception for (g) in matter 11, and delete condition
(c) from 31.1.6 and the exception for (c) at the beginning of matter 11.
3.1.4
Insert into Rule 31.1.4 a new standard:
(h)
3.1.5
Where the water is to be taken and used for the purposes specified in Schedule 31.1D, the
amount of water taken on its own or in combination with other takes reserved for that
purpose does not exceed the relevant limit specified in that Schedule.
Insert new matter into 31.1.6:
(10B) For water takes that are not for consumptive use, the extent to which water is returned to the
water body including rate, timing and location.
3.1.6
In Principal Reasons for Rules 31.1.7:
(a)
Insert new paragraph after paragraph 11:
New information shows that more water can be sustainably taken from the Central Plains
aquifer, although the additional water can only be taken from within a high yield area
adjacent to the river. This means maximum advantage can be taken of recharge of the
aquifers from the Motueka River. Seawater intrusion in the nearby Hau Plains Zone is still
an important trigger for rationing during times of drought. It is possible that seawater
intrusion in this zone is a localised effect and takes from the Central Plains Zone may not
have a significant effect on this trigger. Further monitoring and investigation will
determine the extent to which further water might be made available from the Central Plains
Zone without causing seawater intrusion, either along the coast generally or in the Hau
Plains Zone in particular.
(b)
Insert after paragraph 12:
Separate allocation limits have been introduced for the Dove and Stanley Brook catchments.
They were previously considered part of the Upper Motueka Zone, however only the lower
Dove River (granite reach) reliably contributes flow to the Motueka River in summer.
Allocation limits for both these zones reflect the summer dry nature of the catchments and
Proposed Change 13/Proposed Variation 66 – Water Allocation Review, Motueka Area
Page 10
the security of supply is likely to be less than the stated objective. Water meter information
will help the Council and the water users to understand more about patterns of water use
and security of supply.
(c)
Replace paragraph 14 with a new paragraph:
An allocation limit has now been established for between Woodstock and Woodmans Bend.
The allocation limit is set in relation to flows and allocation limits above Woodstock for the
Upper Motueka Zones and below Woodmans Bend for the Motueka Plains Zones.
Allocation limits for the Motueka Plains Zones, especially the Central Plains Zone, take into
account existing and likely future water demand for the irrigation of irrigable land in the
Motueka Valley.
Allocation limits have now been included for some of the smaller coastal catchments near the
Abel Tasman National Park. Although the Council does not have a good knowledge of the
uses and values of those water bodies, it has introduced a provisional water allocation limit
to help manage reservation of water for potential future water needs of the community and
to provide some guidance for potential water users. The allocation limit may be reviewed if
there is more information about the significance of uses and values in those water bodies.
Effects of takes from rivers with no allocation limit will be assessed on a case-by-case basis
and decisions will be directed by Policy 30.1.9.
3.2
SECTION 31.5: SITE-TO-SITE TRANSFER OF WATER TAKES
3.2.1
Insert after the second paragraph in section 31.5.2, the following new paragraph
Transfer of water takes away from land subject to Maori perpetual leases is a non-complying activity
to ensure Maori landowners will retain access to water for irrigation in the future when they regain
control of their lands.

The area of irrigable land is calculated using soil type, slope, aspect, elevation and rainfall criteria. (Refer to the “Tasman
Regional Water Study Technical Report Stage 1: Land and Climate Suitability for Irrigated Crops, Lincoln Environmental
Report 4487/1, August 2003). Both suitable and marginal soils are included. Unirrigable areas within stopbanks, and land
with high groundwater tables and properties less than 1ha in area or zoned for urban use are excluded. Perpetual Lease Land
for which water permits are already held by iwi is also excluded.
