OOo-gnome default language fc4?

[MR <mstuff pl net>]

Hi All,
I've recently moved up to fc4 and I'm finding I'm not able to set my OOo 
"Default language for documents" to English (New Zealand).  When ever I 
set it, it reverts to English (US) on restart.  Any ideas?

I've set the language at gnome session login to English (UK) - Eng (NZ) 
not available - which causes a warning that I'm not using the system 
default.  This does seem to set the OOo default, but that leads to the 
next questions...
1-How to configure for English (NZ) at gnome session login;
2-How (ultimately) to set the system default to English (NZ);
3-(May be same as 2?)  How to provide alternatives to "English (USA)" 
under "System Settings -> Language"??

I've tried installing English other than US and nothing happens (both at 
install and via "Add/Remove Applications")?

Any ideas (other than conspiracy theories - which I'm coming to myself:)?

Regards,
Morgan.
