"Per capita GDP growth remains relatively sluggish," Gordon said. He also warned that the fall in agricultural output (down 1.6 per cent for the quarter) was worrying given the worst of the dairy downturn was still to flow through.
"We expect the drop in dairying income to weigh on consumption and investment growth over the next couple of years."
Paul Dales at Capital Economics in Sydney said the result wouldn't prevent the RBNZ from cutting interest rates from 2.25 per cent to 2 per cent in the coming months, although it does make it a little less likely that rates will fall below 2 per cent.
Economists at ASB and ANZ, and brokers UBS and First NZ Capital were also picking a further rate cut, most likely in June.
The Reserve Bank last week cut the official cash rate to 2.25 per cent.
Yesterday's figures showed the population grew 0.6 per cent in the December quarter, for an annual increase of 1.9 per cent.
That led to a 0.1 per cent fall in real disposable income per capita, following on from a 0.1 per cent contraction in September. On an annual basis, real gross national disposable income per capita shrank 0.4 per cent.
But Finance Minister Bill English said "despite the dairy industry doing it tough at the moment, we are in the unusual situation of solid growth, more employment and higher wages, but very low inflation." English said.
"The outlook remains for continued moderate economic growth," he said.
