Advice on Water Sector Reform, New Zealand

The problem

The New Zealand government is proposing a major reform of the water sector which would merge the water services owned and operated by 67 local authorities into four mega-entities. The local government sector required a trusted independent economic and strategic advisor to provide constructive analysis of the government’s water reform proposals and provide complementary analysis where gaps existed in the government’s advice.

How we helped

Castalia was separately hired by Local Government New Zealand (LGNZ, the body representing all local authorities), several individual local authorities in each of the mega-entity zones, including Whangārei District Council (WDC) and Timaru District Council (TDC), and a group of 24 local authorities (Communities for Local Democracy, C4LD). We provided a range complementary advice and analysis:

  • For LGNZ: Castalia defined the international best practice evaluation parameters for choosing institutional water delivery forms. We studied the extent of economies of scale in water services available in New Zealand, and assessed whether the government’s evidence base and the economic analysis supported the Government’s case for reform. We carried out comparative institutional analysis (including international and local case studies) of the four major water service delivery models, which improved the government’s evidence base.
  • For WDC and TDC and other councils: Castalia examined the government’s consultants’ modelling of costs and potential cost savings from the administrative mergers. We found that the cost savings were implausible and based on faulty assumptions. We also provided a rebuttal to the government’s response to Castalia’s report to WDC.
  • For C4LD: Castalia provided expert insight on economic regulation in the water sector for a submission to MBIE. Castalia also prepared analysis of three reform options, applying seven neutral evaluation criteria. We found that improving regulation, funding mechanisms and financing for local government, or providing for council-owned regional enterprises were both superior options to the mega-merger proposal.

Impact

Castalia’s advice has highlighted serious flaws in the mega-merger proposal. The local government sector has used Castalia’s advice to highlight deficiencies. The government appointed a working group to address some of the governance and representation concerns voiced by local authorities. Our evaluation framework has shaped option selection, and shifted the public debate. Our economies of scale analysis exposed the faulty assumption that amalgamation is a necessary ingredient in achieving financing and scale benefits. Finally, our analysis has highlighted numerous lessons missed from overseas.
