The booze-fuelled Labour Youth Camp last February that saw a 20 year old facing four charges of indecent assault - has the party saying its code of conduct will be tightened.

The Prime Minister was initially kept in the dark about what went on at the camp at night after she'd spoken to those attending.

A report into it will look into alcohol at gatherings and the supervision of those attending.

Jacinda Ardern says the report wasn't made public because of the pending court case - but says changes will follow.

Ardern wouldn't comment further.
