Hi Kam i came here with my certifiying gas and after a bit of stuffing around with the dropkicks at the board got the recipricole right as a NZ certifyer and from the few licenced guys I know who have gone the other way i believe they have had to do some more study. Not sure if you can do this from NZ though. Best suggestion would be to contact TAFE in one of the states and ask what there requirments are in that regard but if you are Aussie licenced then you definatly have the right of reciprocy
