"Pumpkin prices have reflected lower supply, with dramatic price increases in the last three months, while kumara prices increased more steadily through the year."
Grocery food prices were up 2.4 per cent, with higher prices for butter, fresh milk, and cheese. Annual butter prices increased 48 per cent to reach another record high, Stats NZ said.

Restaurant meals and ready-to-eat food prices increased 2.4 per cent, with ready-to-eat food up 2.3 per cent.
Food prices account for about 19 per cent of the consumers price index, which is the Reserve Bank's mandated inflation target when setting interest rates.
A spike in food prices and a recovery in oil prices earlier this year led to some recent inflationary pressure, although housing-related costs are still the dominant contributor to higher consumer prices.
However, while the central bank lifted its forecast inflation at its November monetary policy review it still does not expect to begin lifting rates until June 2019 at the earliest.
