The assigned official failing to turn up without notice and the lack of an available replacement should not have happened, Raj said.
"At women's representative level there's only a few girls that dominate, so when you have issues like [Watkin's dismissal], it just cuts down a team."
Nonetheless, Raj said the group of players still needed to take ownership of their training outside of game days if they wanted to play representative cricket.
Aside from Watkin, the next highest contribution was the sundries.
Taranaki comfortably picked off the total for the loss of one wicket.
Wanganui's next game will be this Sunday against Manawatu at Victoria Park, while the Taranaki and Hawke's Bay teams will also be playing each other at the ground at the same time.
