Peter Wilson: Week in Politics - NZ First gains traction while GST-free produce fails to hit the sweet spot

Labour will have to do much more than offer families a saving of about $5 a week to get back in the election race, NZ First's support continues to creep up and the media starts looking at where it's coming from, while another poll supports the trend that's showing National and ACT with enough support to form a government.

Rarely has a policy attracted such harsh criticism as Labour's election promise to remove GST from fruit and vegetables.

On the government's own estimation it will save households about $4.25 a week based on an average spend of $32.50.
