There is disbelief the Labour Party hasn't learned from past mistakes.
Jacinda Ardern says she's concerned and frustrated, following reports of an alleged sexual attack on a 19-year-old Labour volunteer by one of the party's staff.
The party this year investigated seven formal complaints about the male staffer, but concluded no disciplinary action was warranted.
Political editor Barry Soper told Kate Hawkesby Labour's already been through this once with a Christmas party incident at Waihi.

- Emails show Labour was sent details of sexual assault allegations against party staffer
- Labour took six months to investigate serious sexual assault complaint
- Second complainant says Labour knew about sexual assault claims
He says it was badly handled, and ended with a young man in court.
Soper says these more recent allegations are much more serious.
“If you're told about complaints in the Labour Party, you should ask what the nature of the complaints are.
"If Ardern didn't ask that, she should've. The Prime Minister is looking like she has egg all over her face."
