Winter vegetables were cheaper in May, Stats NZ says today.

Broccoli, potatoes, and cabbages all fell in price in May.

'The cooler weather brought cheaper winter vegetables,” says consumer prices manager Gael Price.

In the May month, broccoli fell 12 per cent, potatoes fell 3.0 per cent, and cabbages fell 11 per cent.

In the year to May 2019, kumara were 37 per cent cheaper.

'The average price of kumara was $4.86 per kilo in May, down from $7.77 per kilo a year ago, when prices were unusually high after wet weather led to a shortage."

Despite lower prices for winter vegetables, avocados hit a new record high in May. Avocado prices reached $5.73 per 200g, 13 per cent higher than a year ago.

'Avocado prices fluctuate greatly during the year, with supplies typically available between August and April, and prices typically peaking around May or June."

Orange prices rose 18 per cent in May, reaching a record high of $4.58 per kg, while kiwifruit prices fell 42 per cent.

Dairy products cost more in May, after falling in early 2019. The average price of a kilogram of mild cheddar cheese reached $9.57, up from $8.79 in April 2019, the highest prices in almost five years.

Cheese (up 7.6 percent), butter (up 5.1 per cent), and yoghurt (up 2.0 percent) prices were all up compared with April.

'Global dairy auction prices have risen this year. We are now seeing these rises reflected in supermarket prices."

Eggs, both free-range and non-free-range, rose 1.6 per cent for the month as free-range egg suppliers remain under pressure to adjust for the egg shortage.

Overall, monthly food prices rose in May 2019, up 0.7 per cent, and increased 1.7 per cent in the year to May 2019.
