The Labour Party's general secretary Andrew Kirton has resigned.
He will be taking a job at Air NZ.
Newshub understands Mr Kirton had signalled to the party he would leave in 2018.
The news comes as a report into sexual assault and harassment at a Young Labour camp nears.
It's alleged a 20-year-old man assaulted or harassed four 16 to 18-year-olds at Young Labour's summer camp in Waihi in February.
Mr Kirton was made aware of the allegations in the days following, but didn't inform the police or the teenagers' parents.
Wellington lawyer Maria Berryman began the report in March, which was expected to take three months.
Newshub understands the report is still a few weeks away, and is taking longer than expected so a thorough process can be followed.
Mr Kirton spent some time as head of communications at Heathrow Airport.
