New Zealanders may have to cut back on the Friday night fish and chips.

The country's favourite takeaway has been unable to escape the grip of inflation, as businesses face rising costs.

Bluff fish and chip shop Galley Takeaways has been hit and the business has been forced to put prices up.

Owner Diane Williamson says a Blue cod fillet is going for $12.50 this week, plus the scoop on top.

She told Mike Hosking everything is causing costs to blow out.

Williamson says unfortunately fish in the southern region has gone up 10 per cent from mid-April, and while she's reluctant, she's having to pass it onto the customer.
