The economy, as measured by gross domestic product (GDP), grew 0.6 per cent in the December 2017 quarter, Stats NZ said today.
That took annual growth for 2017 to 2.9 per cent.
The New Zealand dollar fell to 73.05 US cents as at 10.50am from 73.30 cents immediately before the release.
Growth was driven by increases in the service industries but was tempered by falls in the primary sector.
Cattle and sheep farming and milk production were the biggest contributors to the decline, due to the wet spring and subsequent drought conditions in the second half of the quarter, Stats NZ said.
