"The issue at stake here is about responsiveness and accountability to the people of Auckland through their elected representatives," Goff said.
"Despite the fact that 92 per cent of the assets of the new entity would come from Auckland, and Auckland would have approximately 90 per cent of the population served by the new entity, Auckland Council could have just 35 per cent of the representation in the governance of the new entity, and would have no direct input into appointing its board," he said.
The new water entity, while being partly owned by Auckland Council, would be run several steps removed from councillors. The council would have a say into the group of people who appointed the board of the entity, but it would not be able to directly appoint the board itself.
Under the current model, Auckland Council's water is run by Watercare, a council-controlled organisation, and Goff said the council was able to control who was elected to the board of Watercare and had some level of control over its strategic direction, as Watercare had a mandate to give effect to the council's strategic plan and long term plan.
"Under the new model there is no accountability and responsiveness to us," Goff said.
Goff accepted the overall thrust of the water reforms, saying that the Government could not make the changes it needed to make to water with 67 separate councils controlling water infrastructure.
But he said he hoped that a different model could be worked out for Auckland, which would belong to a water entity stretching from Auckland to Northland.
Goff said Watercare was "a head and shoulders" above other water providers in New Zealand. Goff said Auckland could be a "centre of excellence" that showed the other four entities the way forward.
"We are the one water services entity already in place. There are three others that need to be set up.
"Auckland could be the centre of excellence that provides advice and assistance to the other water entities," Goff said.
Local Government Minister Nanaia Mahuta's announcement of the incentive programme included a subtle reference for all councils big and small to join up with the Government's reform.
"The reforms are about acting for the greater good, with significant benefits to all communities. But they will have the best chance of success if all councils participate.
"We are working with the sector to ensure everyone understands the reform-related information, and to explain the policy proposals, the benefits of reform, and the details of the support package," Mahuta said.
The Government has been overseeing a reform of New Zealand's stormwater, wastewater and freshwater infrastructure since it took office. It responds to concerns that the councils that own water assets have not been spending enough to maintain them, leading to leaks and contamination.
The reforms would see 67 councils merge their water assets like pipes and reservoirs into four large water entities. Councils would collectively own those entities, which would be in charge of maintaining water infrastructure on behalf of the councils.
The Government estimates that without reform the average household bill for water services could be as high as $1900 to $9000 by 2051.
