British backpacker Grace Millane's murderer has begun the process of appealing against his conviction and his prison sentence, his barrister said.
Auckland-based Rachael Reed QC told the PA news agency: "I can confirm that I act for him and an appeal against conviction and sentence has been filed [in the New Zealand Court of Appeal]."
Lawyers Ian Brookie and Ron Mansfield led the defence of the 28-year-old, who cannot be named due to a suppression order, during his trial.
He was convicted of murdering Ms Millane by strangling her in a hotel in Auckland after meeting her via Tinder on December 1, 2018 - the day before her 22nd birthday.
Ms Millane's body was later found in a suitcase buried in a forested area outside the city.
Last month the man was jailed for at least 17 years for the murder.
A jury in November rejected that argument and found the man guilty.
Murder typically comes with a life sentence in New Zealand. Prosecutors successfully argued that the man must serve 17 years before becoming eligible for parole.
Mr Brookie and Mr Mansfield had asked for their then-client to serve 12 years, later indicating he would appeal.
In sentencing, Justice Simon Moore told the murderer his actions amounted to "conduct that underscores a lack of empathy and sense of self-entitlement and objectification".
Speaking after the sentencing, Detective Inspector Scott Beard of Auckland City Police said the death was "senseless and needless".
