"Overall I am happy. I didn't quite go under the time tonight, but with all the work we have done the main focus was the 100m. The 200m comes as a bonus although I had already qualified in that," Snyders said.
"A time of 27.0 is fast and I felt it last night. Throughout the swim, I kept saying I was swimming fast and it was reflected when I looked at the scoreboard,
"I was only a second off my best. It's my third or fourth fastest time ever so I can't complain too much.
"To be able to swim well this morning and back it up tonight was encouraging. I will look forward to a small break now and then really programme myself ahead to London. I will definitely be targeting finals there."
Snyders finished two seconds clear of Ashton Baumann from North Shore with Otago's Matthew Glassford third.
North Shore sprinter Carl O'Donnell, coached by Scott Talbot, celebrated a hat-trick of titles in the blue riband event, the 100m freestyle.
O'Donnell clocked a personal best 50.11 after turning in 24.1'7 at the 50m mark. He cleared out to win by half a second from 200m and 400m freestyle champion Matthew Stanley with Australian-based Paul Benson third.
Taranaki's Charlotte Webby, who will contest the final Olympic qualifying event for the 10km open water swim in Europe in June, showed her versatility and strength in winning the 200m butterfly title.
Last year's runner-up clocked 2:14.65 to beat off the challenges from the capital pair of Lauren Coetzee and Samantha Lee.
Wellington's Gareth Kean, already under the qualifying time in the 100m backstroke, won the 50m backstroke, a non-Olympic event.
Kean, coached by Gary Hurring, was once regarded as a slow starter but he streaked out to win in 25.54 from Kurt Crosland and Kurt Bassett.
Seven individuals have made qualifying times, along with the women's 4x200m freestyle relay while the men's 4x1200m freestyle relay will await a Fina invitation in June.
