"A further stated assumption is that this sum is funded from borrowings with repayments spread over 30 years. That is a 30-year discharge of liability from council's books. The impact of weather ingress in the 1990s and early 2000s will effectively be paid for in part by future ratepayers who were not even born when the issues arose."
The council has taken responsibility for this area away from one department and moved it to another.
"Legal Services took over the management of the weathertight claims in January. The number of weathertight proceedings on the books is 46, 13 of these in the Weathertight Homes Tribunal, including two multi-unit claims."
The remaining 33 claims are in the High Court, most being multi-unit claims, Darby said.
Darby said he could not tell whether the budgeted amount would cover the actual spending on weathertightness claims.
"The other interesting aspect is the repayments for borrowings are to extend over 30 years. So effectively the weathertightness cost or liability to ratepayers won't be off the books until 2045."
Darby himself has been a leaky building victim and took a claim against the council.
However, he is prevented from speaking about that due to a confidentiality agreement that forms part of his settlement.
The biggest leaky building claim filed names the council.
