Man accused of murdering Grace Millane claims he woke up to find her dead on the floor of his hotel room.

A man has been charged for breaching a suppression order that prevents the name of British backpacker Grace Millane's murderer being made public.

Grace, 21, was killed sometime between December 1 and 2, 2018, by a man she met on a Tinder date in Auckland's CBD.

The killer, whose identity is suppressed until a further order of the court, was found guilty of murdering Grace last month, following a high court trial.

The 27-year-old denied murder and claimed her death was an accident after the pair had rough sex at his apartment. He will be sentenced in February.

On Friday, Detective Inspector Scott Beard said a 63-year-old man had been charged in relation to breaching the suppression order.

The man will appear before the courts next month.

A person can be fined a maximum of $25,000 or jailed for six months for breaching a suppression order.

After the verdict, police investigated six incidents relating to alleged breaches of suppression orders which prevent the name of the killer being made public.

Two people were issued a warning and in another case, there was insufficient evidence available to charge anyone.

SUPPLIED Grace Millane was travelling around New Zealand on her OE when she was killed.

The other two alleged breaches were made by people overseas, meaning they were outside New Zealand Police's jurisdiction.

British press also named him after the verdict, with Detective Inspector Beard reminding New Zealanders it was an offence to breach a court order, including naming someone on social media.

The courts tried to keep the killer's name secret after his first court appearance in December 2018, but despite repeated warnings from judges, the minister of justice, lawyers and the police, the court orders have been repeatedly breached.

Earlier in the year, Google suspended its trending emails in New Zealand and apologised after it accidentally sent out an email revealing the name of the man charged over the British backpacker's death.

At the time, New Zealand Police wrote to the search engine warning it of the court-ordered suppression and urging it to remove the name.

ALDEN WILLIAMS/STUFF Detective Inspector Scott Beard said one person had been charged in relation to naming the killer.

Last month, Justice Minister Andrew Little told RNZ he expected New Zealanders who shared the killer's name on social media to face legal action.

​Little told Morning Report that while work was underway to set up an international agreement on suppression breaches with countries such as the UK, Canada and Australia, the law was very straightforward in New Zealand.

"If somebody in New Zealand goes on social media and publishes details that are suppressed, that's a matter of contempt of court in New Zealand. We've already got the power to deal with that and I understand authorities will be looking at situations where that has happened in the last couple of days."

In August, Little began working with his counterparts in the UK, Canada and Australia to ensure New Zealand name suppression orders were obeyed. The idea was to create a framework that would ensure publications within those countries are held to account for breaching court-ordered suppressions.
