I am indeed in New Plymouth and I do get to Christchurch several times a year. However, if you need software or hardware support in Christchurch then my colleague down there, Steven Sykes, can help you.
In reply to knutson:
Gosh! Is it really 4 years since I sold you that RiscPC, Steve?
I trust that it's running well.
Thanks for setting up the nz-riscos group on yahoo too
There is still a RISC OS user group in Christchurch which meets at Ron May's place on a Friday. I'm not aware of any user groups up Taranaki/Manawatu way, unfortunately.
