Hawke’s Bay Catchments
![Page 4: Andrew Newman, CEO, Hawke’s Bay Regional Investment Company Ltd - Case Study – The Ruataniwha Water Storage Scheme](https://reader033.vdocuments.net/reader033/viewer/2022052621/5583bee3d8b42a7a798b4de3/html5/thumbnails/4.jpg)
Hawke’s Bay has plenty of water
• Hence extensive flood protection infrastructure assets
But is summer dry
• Has significant seasonal limits when the water is most needed and has highest value
• Long-term drying trend
• Very low river flows in typical summers
• Poorer water quality in lowland areas in part coupled with the low flows issue, part
urban
Has traditionally dealt with not enough water solely through a regulatory
approach
• Traditional planning instruments on their own lack flexibility when dealing with change
(average 8 years)
The Water Challenge

Water Management in Tukituki Catchment 1 = problem action & inaction
2 = storage pre-feasibility
3 = full feasibility
4 = full scheme operational assessment & final business case
Following 3 years of feasibility studies, examination of 20+ sites for water storage options (large
and small), and extensive stakeholder consultation, the team is on track for determining final
financial viability by June 2014

Environmental benefits
• Direct environmental benefits =
o flushing flows for removing algae
o increased river flows from irrigation return flows
• Offsetting the economic cost of Tukituki plan change =
o the Plan change will improve the river environment through lifting minimum flows,
setting regulatory limits for nutrients
o the RWSS can mitigate the economic impacts as an alternative source of water
• Estimated value $50 to $80 million

• Water supply business that supplies water to users on volumetric charge basis
Farmer do not have to be, but can be, investors
• Business owns and operates storage and distribution infrastructure – supplies
water to farm gate
• Modified BOOT-like model, with SPV operating business for defined concession
period (70 years)
• Assets revert to HBRC (or its successor) for nil compensation at end of
concession period (Iwi & local investors rights carry through)
• Concession deed with HBRC controls many public good aspects of project
• Water users have long term, take or pay, contracts, but some water available
for spot market

Water Access & Uptake
• We currently hold 110 EOI’s, for 44 Mm3 water or 13,000+ hectares
• 47% of the water under EOI, would equate to 27,500 ha on current
metres cube per ha
• Aiming to contract 40 Mm3 water at financial close
• Contractual elements:
Water Price – 23 c take of pay + 3 cents for pressure
35 year contract
CPI inflator with reset mechanism
Farm environmental management plan
• Opportunity for investment via Information Memorandum for eligible
investors (Irrigators/ Hawke’s Bay Investors)

Summary and Recap Scheme development approach
1. Ensure the scheme is part of an overall catchment water strategy
2. Seek to create regulatory security
3. Seek to manage demand and construction risk through a public private
sector alliance
4. Aim to complete final go no go proposition inside 5 years
5. Take a systematic approach – pre feasibility, feasibility and final business
case.
6. To achieve these timeframes – run work-streams in parallel & resource
adequately

Hurdles/risks/challenges/opportunities
1. Workable consent – April – go – no go
> We’ve lost 3 months in our critical path in this work-stream
2. Securing committed revenue from farmers mid year – go - no go
3. Aligning compatible investors and settling the capital structure mid year – go –
no go
> the final capital structure will fold in behind revenue
4. Keeping the build process & critical path aligned
5. RWSS may create new ground for rural water infrastructure in its approach to
> consenting
> procurement
> capital structure
> Bulk water supply business model
Biggest current risk/opportunity = time and momentum
