But consumers remain more upbeat about their own households' prospects than the economy's.
"Yes, higher petrol prices have hit discretionary cash flow and the weaker New Zealand dollar chills what has been a strong real purchasing power story. However, the labour market remains reasonably solid, mortgage interest rates are falling, and nationwide house prices are still rising," Borkin said.
A net 4 per cent of respondents consider themselves better off financially than a year ago (down from a net 7 per cent last month) and a net 22 per cent expect to be better off in a year's time (a net 26 per cent in June).
A net 34 per cent still judge it a good time to buy a major household item, compared with a net 38 per cent in last month's survey. House price expectations have eased a touch from 5.3 per cent to 5.2 per cent.
"Auckland expectations hit a new high of 7.3 per cent while expectations were flat or eased in all other regions," Borkin said.
