Oldmodels Decals - maker of inkjet decals of New Zealand subjects
The ATR72 decals have been scaled to fit the F-RSIN ATR72-200/500/600 kit. 

The Dash8 decals have been scaled in 72nd scale to fit the Hobbycraft Canada -100 kit, also reboxed by Platz.  Both are generally available form model stockists.  Platz also did a seperate photoetch set.  The first three schemes also contain parts for doing a -300, but there is no current kit.  However I understand some people are converting two -100s to a -300.   
In 144th the -100 and -300 are scaled for the Welsh Models, Sasquatch and NAZCA kits.  The last two are out of production. 
 
The CV580 decals have been fitted to the 1/144 Welsh Models kits and scaled for 1/72.

The Saab340 decals have been fitted to the Broplan kit in 1/72 and Welsh Models kits in 1/144.

The Dash 7 decals have been fitted to the 1/144 Welsh Models kit.

Latest NEW or UPDATED: All Air NZ Trademarks schemes have been updated.  origin Pacific dash 8 sets have been updated.  New registrations added for Air Chathams CV580s.
