Questions around whether it's ethical to expect Maori to pay to return to their own land

National says it'll charge returning New Zealanders for managed isolation if it wins the election ... and the Government is also looking at a plan.

Prime Minister Jacinda Ardern says it as a 'complex area' and legal issues need to be explored.

In London, New Zealander Matiu Workman says it's a ludicrous idea.

He says Maori would be paying for land that was taken from them anyway, and you may as well as them to pay in blankets and muskets and give it back.
