Have a Kiwi mate flying there at the moment. Reality is, that there is not enough local pilots with experience to fill the seasonal work requirements. You need to go to Canada, complete the theory exam, pass a flight test, medical, and be issued with a Canadian licence. To work there you will require an employer to "sponser" you. They seem to be looking for guys with at least 1500+ and plenty of turbine time. I think it is much easier if you have mountain time + sling experience as well.
I'm sure the Canadian pilots on this forum can tell you more.
