Very different campaign launches by the two major parties over the weekend.  

Chris Hipkins launched Labour's in Auckland on Saturday, with the promise of free basic dental care for those under 30 by 2030. 

The following day, in the same city, Chris Luxon went with an eight-point pledge card to voters, but no new policy. 

Newstalk ZB Political editor Jason Walls told Kate Hawkesby Luxon didn't want to take the focus away from the party's just-released tax plan. 

But he says people are starting to poke holes in it. 

Walls says the issue of the foreign buyers' tax has started to rear its head, and Luxon and finance spokesperson Nicola Willis have had to answer many questions about that.
