It has emerged the complaint was made by a former adult member of Swimming Southland against a coach.
Splash Palace in Invercargill this weekend is hosting a Junior Mako event, a competition for junior swimmers, starting on Friday and going for three days.
It is believed Swimming NZ chief executive Steve Johns and diversity, inclusion and wellbeing manager Cherie Harris will be attending the Mako festival.
A document obtained by the Otago Daily Times says the two Swimming NZ officials will be at the meeting should anyone wish to reach out to them.
Swimming Southland, in conjunction with Swimming NZ, is co-operating with an ongoing investigation led by the Sports Integrity Commission Te Kahu Raunui.
The document asked for co-operation in respecting the privacy and confidentiality of all parties involved while the complaint process continues.
It emerged earlier this month a complaint against a Southland swimming coach was sitting with the commission.
No details of the complainant were known at that time but it has now emerged it is a former adult member of Swimming Southland.
Swimming Southland had surveyed current and past swimmers about experiencing instances of harmful behaviour in Southland Swimming environments.
However, that survey happened in 2023 and results were not believed to have been circulated.
A complaint by the former adult member was lodged in 2025 and that was passed up to Swimming NZ from Swimming Southland who then sent it to the Sport Integrity Commission .
The Swimming Southland website said there were just under 1000 registered swimmers in Southland from 11 clubs.
A Sport Integrity Commission spokesperson said earlier this month wellbeing was a priority and it supported anyone involved in a complaint.
Splash Palace was owned and operated by the Invercargill City Council.
The council had not received complaints regarding alleged harmful behaviour relating to Swimming Southland.
Swimming Southland was contacted yesterday for comment but did not reply.
