"These developments have come on the back of a tightening in lending conditions (LVRs) and creep in higher mortgage rates. Initially, the impact of these changes had been concentrated heavily in Auckland."
They also say sales across the country have fallen sharply through mid-2017, "and by much more than the usual winter lull".
"In addition, Auckland prices have continued to fall and are now down 4 per cent since January, while in other regions much of the resilience in house prices earlier in the year has faded."
Wider impacts
Whenever people move home there are costs over and above the obvious.
Often home furnishings and appliances are bought, along with money spent decorating the "new" home. So the current slowdown has impacts on the wider economy and the Government's GST take.
Westpac's economists say looking back to the earlier part of this year, durable goods spending has been relatively flat.
"With mortgage rates expected to continue to push higher, and house prices to continue easing, this signals an important headwind for economic activity over the year ahead."
And though the official cash rate will likely remain unchanged for another year, that
doesn't stop banks increasing their rates by tiny fractions at a time.
Each increase takes a little more cash out of our pockets, away from discretionary spending (and often out of the country to Australia).
And talking of home loans, how long will it be until crunch time comes for the thousands of people who took out interest-only home loans? When these loans start ticking over to capital and interest, and the resulting higher repayments, some people will be in financial stress.
