"Consumer confidence remains high. And why not?" said Sharon Zollner, chief economist at ANZ Bank New Zealand.
"Jobs are plentiful, there's talk of higher wages, and the Auckland housing market has found a floor. Steadiness is the theme, with confidence unchanged versus last month, and no difference between current and expected future conditions."
A net 39 per cent of those surveyed said it was a good time to buy a major household item, down from 40 per cent in February, which ANZ said suggests robust durables spending.
Respondents expected house prices to rise 3.5 per cent per year over the next two years, up from 3.1 per cent the previous month, with Wellingtonians expecting house prices to rise 4.4 per cent. Prices in general are expected to rise 3.4 per cent per year over the next two years, from 3.4 per cent in February.
"To be fair, high consumer confidence can be a mixed blessing at this stage of the economic cycle," Zollner said.
"If it primarily reflects a frothy housing market, it can lead to more borrowing than is prudent, with a resulting boom-bust dynamic in consumption. Fortunately, at present the confidence appears to be founded on solid income growth."
"The strong labour market is supporting household incomes and various government policies are intended to provide a further boost, while at the same time strong commodity prices are boosting exporter incomes. With household debt already at a record high as a proportion of incomes, a steady-as-she-goes housing market is just the ticket."
This survey comes after last Wednesday's release of the second ANZ Business Outlook of 2018, which showed business confidence increased in March on some measures, but most remain below the levels of six months ago. The survey reported a net 20 per cent of businesses were pessimistic about the year ahead, versus 19 per cent in February.
Zollner said ANZ's confidence composite gauge, which combines business and consumer sentiment, "is being supported by robust consumer confidence in the face of hohum business confidence", and remains consistent with GDP growth between 2 per cent and 3 per cent.
