Both are ranked in the top 10 this season and the fact 32-year-old Hewitt finished fourth and 31-year-old Samuels 10th in Glasgow hints all is not lugubrious. However, the next generation of Ackermann, Clarke and Jenkins need to start generating similar performances.
Among the men, Sissons, with a season ranking of 14th, and Dodds at 24th, face daunting circumstances at Edmonton and further difficulties when making a case to HPSNZ. Dodds finished 10th and Sissons 13th in Glasgow - disappointing results against the diluted Commonwealth field.
TriNZ are insured to some extent against a drastic funding cut after pitching an eight-year plan after the London Olympics. A resurgence might not be far off if Dan Hoy, Elise Salt, Tayler Reid and Sam Ward fulfil their potential.
The sport also faces introspection. The ITU like showcasing cities for their main events - the infrastructures and logistics help save costs. But cities are mainly built in flat areas, meaning the races are usually decided on the run.
In contrast to Ironman events there are no penalties for drafting which makes pelotons de rigueur. If those conundrums could be solved, or at least balanced, the sport might become less formulaic to watch.
