Hi, I would identify a few companies you want to work for and send them your CV directly. Congratulations on getting the visa though!
But of course that means having a CV that is well written and to NZ standards and documents your achievements correctly. You don't want to say, miss that one chance when you send a CV - and then it's confusing or hard for them to follow.
CV's here are pretty different to what I've seen in the rest of the world. Tend to focus a lot on achievements, and relevant experience.
NZ employers are usually concerned about having someone who can do the job as well as positive to work with.
