Looking at photos of the NZ Valentines, all of the ones that I can see have the later 'un-spoked' type of wheels, and not the wheels offered by AFV Club.
This is actually true of all six decal options in the AFV Club Valentine Mk.II. The vehicles are quite well photographed, and there is clear evidence, for example in Dick Taylor's book Valentine vol.1, (NZ vehicles on pages 44-48). I am writing a review for AMPS, and this will appear in Boresight magazine in the future. However, it is worth knowing this wheel issue early, so that you (and others) can avoid possible disappointment. I would be delighted to hear from anyone who can locate photos of the vehicles depicted in the AFV Club kit but fitted with 'spoked' wheels.
If you are using the AFV kit as a basis for NZ, as you suggest, you will need to source the later wheel type, the photos seem to indicate.
Hope this is helpful,
