Blessie Gotingco's murder trial could have been jeopardised by the publication of an online work.

The trial of the man accused of killing Auckland woman Blessie Gotingco has resumed as usual in the High Court at Auckland, despite the court having to seek the taking-down of an article about the case written by a court registrar.

An investigation has begun into the actions of the registrar who penned the piece, which appeared on an overseas news website.

In a statement, Higher Courts general manager Paula Tesoriero said the Ministry of Justice was taking the matter very seriously and it was being investigated.

Rules for working with the media were covered in a staff code of conduct which allowed only authorised members of staff to to speak on behalf of the Ministry, she said.

"We have informed the Chief High Court Judge and we are contacting the website to discuss the removal of the story."

Tesoriero said she couldn't comment further because it was an "employment matter".

At the beginning of the trial last week Justice Timothy Brewer reminded the jury panel not to do independent research online but if the piece has been inadvertently seen by a juror, it could have led to the abandonment of the trial.

The trial resumed on Tuesday morning with no mention in court of the incident.

The trial of the murder accused began a week ago and is expected to last at least another week.

The prosecution has so far called more than 25 witnesses and the defence is expected to begin calling their own witnesses in the coming days.

The defendant has interim name suppression to protect his right to a fair trial, but his image is allowed to be published.
