Goodall expects the OCR to rise today and next year. That could put more pressure on values.
Strong economic performance is obvious via low unemployment but strong gross domestic product figures. Goodall thinks that persistent inflation could see the OCR increase further into 2023.
That could prolong the current downturn in values. Restrictive credit rules, such as tight loan-to-value ratios, are also likely playing a role, he said.
The Herald reported yesterday consumers were turning to personal loans to make ends meet, as high inflation and rising interest rates put the squeeze on household finances.
The latest monthly report from credit bureau Centrix shows personal loan demand spiked in August to hit a 10-month high, eclipsing well over $500m in new lending.
It was the first time this year that the appetite for personal loans outpaced levels seen in 2021.
Goodall said that Auckland showed signs of stabilising, with a slight improvement on the fall of 4.6 per cent at the end of August. But it was probably too soon to call it a trend just yet.

Last month, CoreLogic plotted houses in seven Auckland suburbs with $2 million-plus values taking a $100,000 hit.
The country's highest-end housing suburb Herne Bay, upmarket Ōrākei, Waiheke Island's most popular Oneroa, Onetangi and Palm Beach, northern seaside area Omaha in Rodney, and the eastern area of Shamrock Park near Howick suffered the biggest valuation drops out of 201 suburbs measured, CoreLogic said in September.
Herne Bay values fell 2.8 per cent, Oneroa was down 4.8 per cent, Onetangi down 5.7 per cent, Palm Beach down 5.3 per cent, Ōrākei down 4 per cent, Omaha down 7.4 per cent, and Shamrock Park values fell 5.4 per cent.
Today, Goodall said Wellington was continuing to experience the weakest performance of any area nationally. Values across the broader capital area including the Hutt and Porirua fell 2.5 per cent over the month and 8.5 per cent over the quarter, to be 9.1 per cent below the same time last year.
Property values had not fallen as far or as consistently in the Kāpiti Coast District, but after a drop of 1.8 per cent in September, the average value is now 3.7 per cent below the same time last year.
