Millions are required to be raised by ratepayers in unexpected bills for councils' leaky home liabilities. The funds finished over two years when thousands of claims were made.
In order to cover leaky homes claims from the middle of 2002 till 2004, instructions to pay $4 million between them in extra levies to a jointly owned mutual fund have been given to the council. 
The amount was described as "tip of the iceberg" by Wellington Mayor Kerry Prendergast.
She continued, "There will still be more claimsand they can't quantify those."
Councils are fully hit for 20 to 30 per cent of repair costs are also the responsible bodies for inspecting and approving buildings. 
Ms. Prendergast held a viewpoint that the sum of the uncovered bill from 2002 till 2004 was approximately $300,000, but was expected to go much higher.
It should be noted that peak in claims for leaky homes, majority of which were constructed during 1996 to 2002, are covered by the period. 
Local body-owned insurer Civic Assurance manages the fund.
