The Reserve Bank (RBNZ) is now forecasting an earlier - and sharper - period of house price falls, and expects in total that house prices may fall about 9%, starting from the current quarter.
In projections released with its latest Monetary Policy Statement on Wednesday the RBNZ forecast that there would be falls in the prices of NZ houses for each of the next nine quarters (including the March quarter we are in).
The annual rate of price drop would peak at 5.4% in March of next year (2023) the bank said.
In its last series of price projections in the November 2021 Monetary Policy Statement the RBNZ forecast that house prices would not start to drop till the December quarter of this year. And the peak annual rate of fall was only 3.5%.
The REINZ's figures for January showed a significant fall in both prices and sales - which was consistent with the anecdotal evidence that had emerged last year that the market was coming to an abrupt halt.
The RBNZ is predicting that there will be quarterly falls in excess of 1% in each quarter of this year, with the biggest - of 1.5% - projected to occur in the September 2022 quarter.
In the latest MPS document, the RBNZ said house prices have been expected to decline moderately towards more sustainable levels since it published its August 2021 Statement.
"However, the magnitude and timing of house price falls have always been uncertain," the RBNZ said.
"Nationwide house prices fell in December and January.
"Higher mortgage interest rates, policy changes related to investors and tighter credit lending standards are some of the key factors weighing on housing demand."
The RBNZ said its "central forecast" was for prices declining about 9% from the end of 2021 to mid-2024.
"The assumed slowdown in prices also reflects a significant increase in supply of new homes at a time when there is near zero net migration. Nationwide residential building consents are at record high levels, and residential construction is assumed to remain high for at least the next few years."
