A sentiment indicator drawn from this survey and ANZ's monthly business outlook survey points to growth accelerating to 4 per cent by early next year.
"Doubts remain as to whether the supply side of the economy can in fact deliver these rates of growth without blowing a gasket," Bagrie said. "However, anything around or slightly north of 3 per cent would put New Zealand among the strongest performers in the OECD next year."
Meanwhile ANZ's monitoring of job advertisements recorded a 1.1 per cent rise last month to be 4.1 per cent up on a year ago. That includes a 0.5 per cent rise in internet ads.
"In recent years tepid growth in internet job advertising has been matched by an unemployment rate that has stubbornly refused to fall," said ANZ economist Sharon Zollner. "The indicator is finally tentatively turning upward, but it is still a long way from indicating a marked dent in the unemployment rate in prospect any time soon."
The economic expansion had been broadening, Zollner said, but consumer spending was showing signs of running out of puff.
"In that context the evidence [of] an upward trend in job ads - albeit mild - is encouraging as it presages income growth for households."
