Tauranga swimmer Nathan Capp saved the best until last, with a national record in the final event to join the three established swim stars in qualifying for December's FINA World Short Course Championships.
Capp was in a league of his own in the 1500 metres freestyle at the New Zealand Short Course Championships in Wellington, taking 16 seconds off Danyon Loader's 22-year-old record with a new time of 14:38.74.
He qualifies for the team to compete at Doha in December, where he will join Lauren Boyle, Matthew Stanley and Glenn Snyders.
The world championships will round out an impressive year of performances for Boyle, who will defend her 800 freestyle world title at the event.
Snyders has also enjoyed an excellent international season claiming a bronze medal in the 100 breaststroke at the recent Pan Pacific Championships on the Gold Coast and making the final in the same event at the Commonwealth Games.
In other swims on Saturday night Howick Pakuranga's Daniel Hunter won the men's 100 freestyle in 48.63 while North Shore's Laura Quilter took the title in the women's event in 54.30.
Junior Pan Pacific medallist Bradlee Ashby took honours in the men's 200 butterfly, Charlotte Webby won the women's 200 butterfly, while in the 50 backstroke events there were victories for Andrew Trembath and teen star Gabrielle Fa'amausili.
