New Zealand, Australia, and the South Pacific are very well represented among the HJG B737-300, -400, and -500 texture inventory .... with customized aircraft base packs/models/FDE, panels, and sounds to support these.
With the exception of the current B737-300/400/500 panel which is FS2004 only compatible .... all of these files are FS2004 native and FSX portable.
"DEEKNOW's" commented (above) that the HJG offered B737-400 model may be P3D "V3" (only) portable .... and if that's the case then the B737-300 and -500 models should also be similarly portable too.
I can't guarantee such P3D "V3" portability might apply to all other simulations currently offered by HJG though.
For both "proprietary as well as technical reasons" there's no possibility of HJG having these simulations upgraded for later/more recent FS platforms .... sorry

Below's a complete list of all HJG offered B733, B734, and B735 (only) textures for New Zealand, Australia, and the South Pacific operated aircraft over the past 30 years ....
