Question about NZ distiguishing patches - JAYFORCE (BCOF)

[Paweł Wawa]

Gentlemen,
I am a military historian from Poland, interested (among others) in WW2 British & Commonwealth unit/colour/distiguishing patches & badges. May I ask you for some help about last type (I mean used from 1945) patches, that were worn in 2nd NZ Division, mentioned in a title? I have recently found some pictures and description of them, so I know that were made in wool serge, sometimes in felt, and (in Japan) were also silk embroidered. Could you, please, tell me, which units of 2nd NZ Div/9th Bde used: the white one, the tricolor one (similar to EME/workshops, but with a white stripe instead a yellow), the (royal) blue one and a black one? I have found a great photo of theme (in a larger group, from a private collection), but, sadly, without any description...
Any information will be really welcome.
Thank you in advance,
Paweł
