Promises have been made at the ACT party's annual conference over the weekend - but a challenge has also been laid down to the National party.

Party leader David Seymour delivered a speech promising that if they got into government they would begin an investigation into the handling of the pandemic while also repealing a number of Labour's policies.

Seymour criticised National for coming in after a Labour government and not making enough changes, but he says he wouldn't let that happen this time around.

ACT leader David Seymour and National deputy leader Nicola Willis joined Mike Hosking.
