Four government-appointed commissioners will replace elected councillors of the heavily indebted Kaipara District Council.
Kaipara's debts total $80.7 million including about $60 million for the Mangawhai sewerage scheme, prompting the council to propose a 31 per cent average rate increase, which outraged ratepayers.
Local Government Minister David Carter said there had been a review of the council by a government-appointed Kaipara Review Team.
The council requested the appointment of independent commissioners earlier this month after being briefed about what was in the review team's report.
Mr Carter said the team had identified that serious governance and financial challenges facing the council were beyond the councillors' ability to resolve.
