An anti-monarchist group says New Zealand may ditch the Royal Family as our head of state in the not too distant future.

Prince Charles has given the green light to any Commonwealth country if they want to become a republic if it wants to.

15 countries currently have the Queen as their head of state, including New Zealand.

New Zealand Republic chair Lewis Holden told Heather du Plessis-Allan it will depend on Queen Elizabeth's death.

“The end of the Queen’s reign, I think will be a huge epoch in terms of our history and around the world, and I’d expect, actually, that the change would happen relatively soon after that.”
