Fiji managed two podium finishes on day one of the Oceania Swimming Championships in Auckland.
William Clark touched home third in the men's 100m backstroke in a time of 1:00.93 while Fiji also finished third in the mixed 4x50m freestyle.
New Zealand swimmers won six finals and Australia five on the opening night.
Papua New Guinea and Tonga are also in attendance in Auckland but PNG assistant coach Ryan Pini says their results are unlikely to change the make-up of their squad for the Commonwealth Games.
"I believe we have six swimmers heading away to that. The team has been selected from our national titles - it's sort of done that way just to give the team a bit more time to prepare. It's probably maybe still up to the committee to decide but I think we have our team selected".
175 competitors from 14 nations are competing at the Championships, which run until Friday.
