The task of inspecting 11,500 Auckland houses whose owners are fighting council valuations is nearly two-thirds complete.
The Auckland Council's valuation services team leader, Peter McKay, said registered valuers had visited, and in many cases been inside, 7000 houses throughout the city in the biggest revaluation exercise undertaken.
A further 4500 properties were yet to be examined, a task he expects will be finished around spring. Extra valuers had been contracted to assist.
But about 30 to 40 homeowners remain dissatisfied and are taking matters a stage further, lodging a court challenge. They could go to the Land Valuation Tribunal for a final decision if further negotiations with the council are unsuccessful.
Mr McKay said he was not concerned about the big gap between new valuations and sale prices, after a string of houses in desirable Auckland suburbs went for about twice their valuations.
