The national president of the Mongols Motorcycle Club says his mental health is suffering and he wants more phone calls with family and someone to mix with “inside”.
He recently asked the High Court at Wellington to order an improvement in the conditions he is held under pending a full review of the conditions.
Justice Peter Churchman refused.
“Mr Thacker has not been a model prisoner,” he said in his decision.
Thacker was a “501” deportee from Australia in 2018 on character grounds. He was arrested in New Zealand in 2020 on drugs, firearms and other charges.
His behaviour in prison has led to a number of restrictions being imposed on him, the judge said.
Since October 2020 he has been in a “prisoners of extreme risk unit” or PERU. It was previously reported that the terrorist who murdered 51 people in the 2019 Christchurch mosque attacks, was in the same unit.
