Imiller...congradulations on your commercial licence you have just passed a very big hurdle on your way to an aviation career. You certainly will not have a career without a CPL.
I also am a Kiwi and have been in exactly the same position as you. My opinion is you have at this stage two options
1. Go and work as a loader driver for an Ag operator and hopefully getting a few hours up with maintenance and ferry flights and possibly obtaining an ag rating with your employer which can be worked off.(If he is an E cat and if you want to be an Ag pilot) or
2. Do an Instructor rating which can also be worked off with most training organisations. You will get alot of hours but will not be paid much until you get a bit more experience. There also is the problem of 200 PIC before you can obtain an instructor rating.
The way I got hours was part time work at a training organisation doing ferry flights and small commercial jobs until I had enough PIC for the instructor rating and then I was away.
Gook luck
