Convicted killer Colin Bouwer’s latest bid for freedom will be heard later this month.
Bouwer will appear before the New Zealand Parole Board on August 22.
He is serving a life sentence for murdering his wife, Annette, by administering a lethal cocktail of drugs intended to mimic the symptoms of a rare tumour, between September 1999 and her unexpected death on January 5, 2000.
He appeared before the parole board last year but was deemed an "undue risk" and parole was declined.
Bouwer is subject to a deportation order and will be returned to his native South Africa when parole is granted.
At his last hearing, Bouwer raised the possibility of lodging an appeal against his conviction with the Privy Council.
He claimed he assisted his wife to commit suicide when she became ill, as part of a suicide pact between the pair.
He "did not tell his side of the story at trial, after legal advice not to use the euthanasia explanation", Bouwer claimed before the parole board.
Bouwer’s lawyer, David More, earlier told the Otago Daily Times no appeal had been launched as Bouwer was suffering from illness.
When contacted this week, Mr More said he could not comment on the matter as he had "no authority to discuss his health".
No application for compassionate release or temporary release for medical treatment had been received from Bouwer, a parole board spokesman confirmed.
Compassionate release was granted only in exceptional circumstances, he said.
In September 2001, Bouwer was jailed for a minimum non-parole period of 13 years.
That period was increased to 15 years after an appeal by the Crown.
Following his wife’s death, Bouwer travelled to South Africa and returned to New Zealand bald and without his trademark beard.
He told people the changes were a result of chemotherapy he had for prostate cancer.
It emerged that story was false.
