Same where I'm from (Wanaka/Queenstown). Roofing has NOTHING to do with us. A separate trade altogether! In all honesty, it should be a 3 day exam (like in Germany). Not a 3 hour exam. Reason is simple. With the 3 hour exam, you only get about 13 main questions and some of those being linked together. Problem with this being if you get 2 or 3 wrong, you've just lost a shit load of points. With a 3 day exam, you may have over 300 questions, but you've a lot more ground to make up on areas you may be unsure about. I know, I've done both.

one question i got in a nzqa exam was...clearley draw and label a bossed lead roll...?...of course i failed this one...i later asked my boss of over 25 years exp what exactly a bossed lead roll was...he had no idea of course...i later found it in the doyles book...what a f***in joke...they harp on about continued professional development when they cant even keep there training data up to date with revelent practices in the trade!...as well bossing a lead corroner and also bossing a lead pipe flashing...when all merchants sell them anyways...in 4 years i never made any pipe flashing...they gotta move into the twenth centry with there training practices...i dont mind running over these old tecniques for a basic understanding but to have it as a requirment of nzqa is a complete joke.
