NZ students prepare for Friday's climate strike

Young people preparing for Friday's school strike for action on climate change reckon they've already won half the battle.

Some of the young activists met in Wellington to paint banners where Year 11 student Tony Huang told our education correspondent, John Gerritsen, that his parents support his decision to join the protest.
