One of the Labour Party summer camp assault victims says he never expected to be at the centre of a political firestorm.

A 21-year-old man's been discharged without conviction.

He'd initially faced five counts of indecent assault following the camp near Waihi, in February last year.

But he reached a plea deal mid-trial, pleading guilty to two amended charges of assault.

The judge said the man's actions were born out of drunken behaviour.

One victim, speaking exclusively to Newstalk ZB, says he feels the justice system let him down. 

He says he is worried for future sexual violence complainants.

"There was anger there, there was also aspects of fear. If I have gone through this with no justice, what about everyone else who goes through this system?"

He says that the whole saga, which began earlier this year, has been tough for his family.

"I still can't get my head around how it happened. I struggle to understand all of it. My parents have just gone through hell. It's probably been harder on them than it has on me."

He says the judge's comments about 'drunken stupidity' highlighted how the system is failing.

The victim does hope that the man can realise the hurt he's caused.

'I really wish you the best and hope that you can move on with your life and do something positive, but just know how much pain you've caused to all of us, not just me. It's never just been me, it's been the other victims, my family, the other victim's families."

Prime Minister and Labour leader Jacinda Ardern would not comment on the charge, but told media she has been speaking to the victims.

"I've had the opportunity to meet with some and continue to meet with others. So while it is not for me to comment in the public domain on sentencing that is made independently by judges, I will take the time to personally meet with those who've been involved."
