Another of the men charged after allegations of historical sex abuse at Auckland's Dilworth School has lost name suppression.

However, the man cannot be named, after he indicated he would appeal that ruling.

The man, who is in his 70s, faces four charges of indecently assaulting three boys under 16 in the early 1980s.

Today's name suppression hearing was before Justice Mark Woolford at the Auckland High Court. The man was not in court.

Crown lawyer Brian Dickey argued for name suppression to lift, a position supported in court by NZME, publisher of the Herald and Newstalk ZB, and other media organisations Media Works, RNZ, Stuff and TVNZ.

Justice Woolford ruled that name suppression should be revoked, but Claire Farquhar, appearing for the defendant, indicated that decision would be appealed - meaning his identity is kept secret, for now.

In his submission, Dickey noted media stories about the alleged abuse at Dilworth had given rise to other complaints, and the man had worked at another school since the time of his alleged offending.

"There is a potential group of complainants - I can only say potential, because the Crown can't say he has offended again...but until his name is published, there can be no certainty.

"We should confront that now...and then what comes out, comes out."

Seven former Dilworth teaching staff have been charged with a number of serious offences, many of them sexual, against 17 victims. The charges relate to offending between the 1970s and late 2000s.

All seven men were initially granted name suppression after their first appearances, but Alister Harlow, Ian Wilson and Ross Browne, the school's former chaplain of 26 years, lost name suppression earlier this month.

More than 70 people have come forward to police since the arrests.

Dilworth has apologised for the way it previously handled historical allegations but says there are new processes in place and management will support any former student who would like to go to police now.

Headmaster Dan Reddiex, who was appointed last year, said on the day of the arrests that the school had zero tolerance for abuse of any kind.

"The health, safety and wellbeing of our students is our single greatest priority and responsibility.

"We know that a safe environment is instrumental to our students flourishing both personally and academically."
