Evidence is growing that the housing market is heading into a significant correction as it goes into its peak selling season.
Probably the most compelling evidence is the movement in the Real Estate Institute of New Zealand's House Price Index (HPI) over the last three months.
Back in November, just seven of the 28 urban districts measures by the HPI were showing a decline.
By December that number had doubled to 14.
And January's figures were even more compelling, with 23 districts showing declines and just five showing increases..
Those are the changes are from the previous month, but perhaps even more important in the January figures was the fact that the HPI was lower than it was three months previously in 18 of the 28 districts, with nine showing increases and one district (Napier) being unchanged.
And of the nine districts showing price increases over three months, five were showing decreases from the previous month.
Clearly, there is now an easing price trend and it is gaining momentum.
The REINZ HPI is one of the most reliable measures of price movements because it is comprehensive, being based on all residential sales recorded by the REINZ.
It is also a leading indicator because its data is based on sales as they become unconditional.
While other measures such as average and median prices are also useful tools, they can be skewed by the composition of sales each month.
If a greater proportion of sales activity takes place at the top end of the market it can push up average and median prices even if prices of individual properties haven't moved and vice versa.
The HPI adjusts for changes in the composition of sales each month, to give a better indication of overall price movements.
What is not known is how far prices may fall or long the correction may last, but it's off to an impressive start.
The National HPI was down by 1.5% in January after being down just 1.0% in December.
In the critical Auckland market the regional HPI was down 2.6% in January after falling 2.3% in December.
The February and March figures will be important because they are usually the busiest months of the year, after which sales start to slow again as we head towards the quieter winter months.
But evidence, such as slowing auction sales and a greater degree of buyer caution, suggests the correction has some way to run.
The table below shows the latest HPI figures for the main urban districts.
