New Zealanders are in a strong borrow-and-spend cycle, fuelled by strongly rising house prices, according to Westpac's chief economist Dominick Stephens.
In his latest Home Truths commentary on the housing market, Stephens said house prices were continuing to be pushed up by low interest rates.
"The New Zealand housing market remains red hot," he said.
"The REINZ House Price Index has now risen 6.9% over the past three months, which is the fastest three month gain since 2005.
"And a wide tableau of other indicators all point in the direction of house prices continuing to rise rapidly in the coming months," he said, pointing the finger at low interest rates as the culprit.
"Our assessment is that low interest rates are the key driver of the market at present," Stephens said.
"Low interest rates also help explain why share prices and commercial property prices are rising at the same time as house prices.
"Rising house prices have sparked a strong borrow-and-spend dynamic across the economy.
"When house prices rise, home owners tend to spend some of their increased wealth.
"Meanwhile, house buyers need to borrow more, and they are able to do so courtesy of low interest rates.
"The net effect is that the nation borrows and spends," he said.
And he doesn't see that pattern ending anytime soon.
"Once it gets going it can develop a life of its own," Stephens said.
"This self-reinforcing cycle tends to continue until a circuit breaker comes along to end the party.
"Last decade a sharp lift in interest rates was the circuit-breaker, but we don't expect a repeat of that anytime soon.
"In fact, we can see no circuit-breaker at all over the coming year or so, which is why we are forecasting such strong house price inflation over that period," he said.
