The night was finished by outstanding North Shore swimmer Lauren Boyle who beat her own national record in winning the 400m freestyle.
Stanley was in a class of his own in the 200m freestyle clearing out to win in 1:47.57 which is 6/100ths of a second inside the national record set by Loader in winning gold in the 1996 Atlanta Olympics.
Watching from the stands was Loader who was thrilled with the performance. "I've watched both nights with Graham Laing who was his old coach before he moved to the High Performance Centre and Graham is the son of my coach," said Loader. "He is a really good talent and you know if he did that 16 years ago it would have won him a gold medal."
Stanley said he was now resetting his sights on performances in London.
"I came here to get multiple qualifying events for London. I've achieved that and I am excited about it. But I don't just want to attend the Olympics, I want to achieve, so there's a lot of hard work to come."
Stanley, Steven Kent (North Shore), Dylan Dunlop-Barrett (New Plymouth Aquatics) and Andrew McMillan (Cromwell) met the selection standard and will form a national relay combination to attempt to qualify in the 4x200m freestyle relay tonight.
Kean posted the fifth-fastest time of the year in his morning heat of the 100m backstroke in 53.58 and was slightly slower in the final, winning in 53.84.
Daniel Bell, 21, coached by Thomas Ansorg at North Shore, came out of the wilderness after a challenging few months to finish second in 54.39 which was 1/100ths of a second inside the Olympic qualifying mark.
Boyle was also in a class of her own in dominating the 400m freestyle in 4:05.83 which shaved 3/100ths of a second off her national record set at last year's world championships and was also almost four seconds under the Olympic time.
In other finals, North Shore's Penelope Marshall, a member of the women's freestyle relay team which made the final at the world championships, showed her versatility in winning the 100m backstroke in 1:01.78 from teammate Melissa Ingram; North Canterbury's Natasha Lloyd, 16, won the 100m breaststroke in 1:11.38, while North Shore's Samantha Richter broke the national record twice, clocking 26.66 to win the non-Olympic 50m butterfly.
