A euthanasia advocate who failed to disclose three overseas murder charges has been censured and had his registration as a laboratory scientist cancelled.
Sean Davison applied to the Medical Sciences Council for the registration in 2017.
As part of the application, he admitted to a conviction relating to the suicide of his terminally ill mother - a case which made headlines when he was convicted in the High Court at Dunedin in 2011.
He did not admit involvement in three South African deaths, involving a person diagnosed with motor neurone disease, one with a brain injury and a quadriplegic.
Davison was convicted of all three murders in South Africa in 2019.
