The Government is clamping down on arriving travellers at the border.

It's making several biosecurity law changes including doubling the fine for people who don't declare fresh fruit and meat, to 800 dollars.

Biosecurity Minister Andrew Hoggard told Mike Hosking that they want to deter behaviour that puts New Zealand at risk.
