"But we have done a lot of hard work since Glasgow. We did a thorough debrief, made some changes and there's been very good work done in the last period since Glasgow."
New Zealand's leading women, Christchurch's Hewitt - who sits fifth on the world series rankings - and Wanaka's Samuels, who is ninth, Whangarei's Simone Ackerman (No 46) and Kate McIlroy of Wellington (No 51) are lining up, while New Zealand's best men, Ryan Sissons (No 14) and Tony Dodds (No 24), will be on the start line.
There are a host of under-19 and under-23 competitors but the onus is on the elites to front up as the shop window of the sport.
Fraine hopes there will be a rub-off from the Stockholm result.
"Stockholm perked everyone up, even those who weren't there - the culture in the team is such that they were all excited to see those performances.
"It was a tough day with the weather, cobbles and course, it was very timely to build that confidence ahead of this week."
The Edmonton race will provide close to double the normal points through the earlier legs, and so there is the prospect of a top 10 finish overall for Sissons and perhaps even better final positions for Hewitt and Samuels.
Fraine described the Edmonton layout as "a good, solid course". The swim leg is in a lake with an island in the middle. The bike leg has two laps of 11km and one of 5km.
