The South African-born shooter struggled for the Pulse in the final rounds of this year's ANZ Championship but she was playing in a new team, with new midcourters, against relentless Australasian defenders. In the national fold, she would be back in her 'happy place', being fed by the likes of Laura Langman and Maria Tutaia.
The group fixtures against minnows represented an ideal opportunity to regain her form, allowing her to be an asset when the tough matches rolled around.
And van Dyk needed to be reminded that the ANZ Championship is a little like Super Rugby - form in the franchise competition is an important barometer for international performance, but it isn't everything. On many occasions we have seen players regain their spark once they are surrounded by international team-mates, after less than stellar seasons in the transtasman competition.
It might also be time for Netball New Zealand to reconsider their selection parameters around major events. The national body have consistently demanded long-term commitment from aspiring Silver Ferns.
As an example, in 2012 at the start of the current cycle, players were expected to be available for the Commonwealth Games and 2015 world championships in Sydney.
Instead, it might be more prudent - given New Zealand's smaller pool of talent compared to Australia's - to pick the best possible team for each major event in isolation.
Yes, van Dyk probably won't be among the two best shooters in the country next August but it's hard to argue she isn't at the moment. Other players, like mother-of-three Donna Wilkins, may not be able to commit to regular tours and post-season series but might have made herself available for a one-off tournament.
