Five of the seven individuals named have qualified in multiple events. The line-up comprises 2008 Olympians Melissa Ingram, Glenn Snyders, Daniel Bell, Natasha Hind, Hayley Palmer and Lauren Boyle. Others to step up from the Delhi Commonwealth Games team include Gareth Kean, Amaka Gessler and Penelope Marshall.
The newcomers are Wellington teenager Samantha Lucie-Smith and Matthew Stanley, who broke the long-standing national records of Danyon Loader in the 200m and 400m freestyle to qualify.
Secretary-general and selector Kereyn Smith said watching the athletes achieve the tough New Zealand Olympic Committee selection criteria during the week was satisfying.
"I'd like to congratulate the group of athletes who have exceeded expectations this week," she said. "We look forward to this large team of swimmers making us proud in London."
Swimming New Zealand chairman Ross Butler said he was delighted with both the size and quality of the team.
"There have been some outstanding performances at the Olympic Trials and at pinnacle events, and the team going to London has more performances ranked in the top 10 in the world than any other New Zealand Olympic swimming team in recent times," Mr Butler said.
