A Ministry of Health review three years after euthanasia became legal might re-ignite debate.

The Ministry is asking people to share their thoughts on the Act.

It says 344 people had an assisted death in the year to March 31.

General Practice NZ chair, Bryan Betty, says the Act is working as designed.

But he says some groups and people still strongly oppose it, despite its rigorous safeguards.

"The reason for doing a review like that is to uncover those types of issues and to see how this has been operating - and if there are any things there that we should be thinking about going forward."
