"Up until the minister's announcement, council was anticipating that we would have the opportunity to ask our community by way of a referendum on whether they supported the reform proposals," Cameron said.
"We had scheduled this for when the reform proposals had reached the Select Committee stage in Parliament as we believed by this time we would have the final model and answers to the outstanding issues we and other councils have been asking about."
The council was "not happy" that an opportunity for the community to have a say had been taken out of its hands.
"Despite inclusion for all councils being mandated, we call upon Government to continue its stated 'partnership-based' approach by answering our outstanding questions and concerns, and confirming that earlier promises to support Council with the transition will be honoured," Cameron said.
Although the Government had announced the establishment of working groups to address those issues, the mandate had "deepened the feelings of mistrust and apprehension held by many in our community toward the process, and what they see as Government over-reach".
"We feel strongly that Government now needs to do everything it can to satisfy any outstanding concerns specifically around ownership, local voice and control of water assets," Cameron said.
"And further to this, other significant reforms such as to the Resource Management Act and the future role of local government, should be put on hold until the Three Waters issue is fully resolved."
Cameron said some people had incorrectly interpreted his October 27 personal comment welcoming the end of uncertainty around the reforms as support from the council for the Government's actions.
