Van Dyk has been particularly quiet. She is seventh in the list of goals tallied, having put up 150 fewer shots than league leader Jhaniele Fowler, of the Steel, over the first seven rounds. Latu is fourth on the list, but still well back from the top three scorers this season of Fowler, Romelda Aiken (Firebirds) and Caitlin Bassett (Fever).
Silver Ferns coach Waimarama Taumaunu acknowledged the shooting volume of the pair is a concern for her.
"In Irene's case I do think it was a one-off, but with Cathrine the volume has been slightly more of an on-going issue with her, but I think we're settling a couple of feeding lines in front of shooters and that connection takes some time to get right," said Taumaunu.
The lacklustre form of van Dyk and Latu has heightened concerns over the number of shooting imports playing for New Zealand franchises. Along with the Steel's Jamaican import, the Tactix key scoring weapon is English shooter Jo Harten, while Australian international Caitlin Thwaites takes on the bulk of the shooting duties at the Pulse, alongside former Silver Fern Donna Wilkins, who has ruled herself out of national selection for the past 11 seasons.
With the Kiwi franchises reliant on imports to fill key shooting roles, there are limited development opportunities for young local players, which is crippling New Zealand's depth in an area of court they have traditionally struggled.
Taumaunu said while she would like to see more young goal shooters developed, the presence of strong international shooters in the competition has helped a couple of young goal attacks to build their game.
"If you look at someone like [Tactix shooter] Sophia Fenwick for instance, she has been given great opportunity to build her confidence and grow her game with the likes of Jo Harten behind her, she has shown huge improvement this season," said Taumaunu.
Although she was forced to take the rare step of benching van Dyk last week, Magic coach Noeline Taurua is backing her star shooter to respond strongly against the Central Pulse on Monday night, following last week's poor showing, in which she was kept goalless in the third quarter of their 12-goal loss to the Adelaide Thunderbirds.
