The head of the New Zealand Athletes Federation has urged parents and athletes seeking resolutions to abuse within the gymnastics community to not use Sport New Zealand's Independent Complaints Mechanism.

In a massive slap at the Government sports agency, Rob Nichol said the process was not competent and was "unfit for purpose".

Over the past week, the Herald has outlined multiple allegations of abuse of athletes in the country's elite gymnastics programmes, including girls as young as 8 being fat-shamed, forced to train through injuries and verbally abused by coaches.

Outgoing CEO of Sport NZ Pete Miskimmin has urged those affected to use the ICM, which was set up after the investigation into the culture of Cycling New Zealand following Anthony Peden's resignation.

Peden, CNZ's former sprint coach, quit in 2018 after a raft of damning allegations - including a culture of drinking and a lack of accountability within the organisation.

"This is an extremely sensitive situation for parents and athletes. They need a totally independent voice that is professional and competent," Nichol said.

"This is just the system reviewing the system and we have seen in other sports, like hockey, it just doesn't work."

Nichol said they could have good people working on any investigation, but the "outcomes were always mitigated" against by the process.

"We're cautioning parents and athletes against using it because we have used it and it doesn't work.

"Once again we find ourselves in a situation where the system is reviewing itself."

Nichol said the gymnastics situation was incredibly delicate and needed oversight that was totally independent.
