The Labour MP says her proposed law change to legalise assisted dying in New Zealand will not go into the private member's bill ballot.

The bill, drawn up with Wall's wife, human rights lawyer Prue Kapua, and Otago University Dean of Law, Professor Mark Henaghan, proposes an ethics committee be set up to vet applicants and work out the details of the authorised death.
