Hewitt, who finished seventeen seconds behind American winner Gwen Jorgensen, was the best of the New Zealanders today with Tony Dodds racing strongly for 10th place in the men's race that was won by Britain's Alistair Brownlee.
Nicky Samuels was 18th, Kate McIlroy 26th and Ryan Sissons 20th in their respective races.
Hewitt spoke of the disruption to her programme with fiancee and coach Laurent Vidal suffering a heart attack some weeks ago.
"I had two weeks in France with Laurent at the end of April, I was at the hospital twice a day every day. During that time nothing was structured, it was difficult but that is past us now. This gives me confidence for Glasgow, I had a good swim, right up in the middle with that front group."
New Zealand will now be represented tomorrow morning (NZT) in the mixed team relay championships, with Tom Davison, Sam Ward, Sophie Corbidge and Simone Ackermann flying the flag for the Kiwis.
