Dairy product prices, including those for butter, fresh milk, cheese and yoghurt, continue to push food prices higher and households are finding it harder to put food on the table.
Statistics New Zealand figures released yesterday showed food prices increased 3% in the year ending September, following a 2.3% rise for the year to August.
Consumers price index manager Matthew Haigh said for every $100 spent on food, New Zealanders spent about $10 on dairy items.
Butter prices continued to increase through the month of September to their highest level.
The price of the cheapest available 500g block of butter was $5.55 in September, up from $3.48 in September last year, he said.
Wet weather this year contributed to an increase in vegetable prices which were up 6.5% in the year to September. Higher potato and kumara prices contributed to the rise.
