"While the average asking price outside Auckland is up a healthy 7 per cent, the Super City's slow market is dragging the national average asking price down, given it makes up 35 per cent of the country's listings for sale," he said.
Hawke's Bay asking prices rose 20.4 per cent in the last year and listing volumes there are up 20 per cent in September.
In Wellington it was 10 per cent but Canterbury asking prices rose only 0.2 per cent.
