Opshop frontman Jason Kerrison is returning to his roots to help celebrate Fonterra's 10th birthday next month.
Kerrison, who was born in Invercargill, will perform at a free family day, the Fonterra Shout, at Anderson Park in the city on October 24, supported by Tokanui sisters Annah Mac and Kristen Macdonald.
The dairy co-operative is marking the anniversary with six events in the country's main dairying regions, with farmers manning the barbecue and handing out ice creams. The event will be held from noon to 4.30pm.
