Spectacular drone footage shows scale of School Strike 4 Climate in Auckland

Drone footage of Friday's climate action march in Auckland shows tens of thousands of people calling for more to be done against climate change.

The Auckland protest was accompanied by demonstrations in towns and cities all over the country and came after massive protests around the world a week ago.

Many of the participants were students, inspired by Swedish teen climate activist Greta Thunberg.

Drone footage supplied to Newshub showed a birds-eye view of the streams of people holding signs donning bright colours walking down Queen Street. 

Around 90 businesses also pledged their support to the cause, signing up to the Not Business As Usual alliance and giving their blessing for employees to attend the protest.

Many universities around the country also supported their staff and students attending the event, with the exception of the University of Auckland.

The protest also caught the eye of Thunberg herself, with the young Swede retweeting various video and images of the event.

"New Zealand leading the way into Friday," she wrote in one message.

"Early reports speak of 170,000 people on #ClimateStrike in NZ. Or, 3.5% of the population."
