It seems dairy prices are on a roll

Prices at the latest Global Dairy Auction are up by 4.2 percent.

The biggest increases were for skim milk powder - up by 10.3 percent and lactose - up by 7.9 percent.

It's the fourth lift in prices in a row, following a nearly 20 percent fall from around May to November last year.

Andrew Kelleher from JMI Wealth says there's been a bounce back, particularly with skim milk, which is one of the more important components.

He says farmers will be happy and it will give the agricultural sector a bit of confidence.
