Evening Guys

This is my first post and hopefully you guys are the ones who can help me.

I will be gaining my JAR PPL from the UK very soon.

I am thinking of doing my CPL / Frozen ATPL in New Zealand.

Can you please suggest schools that:

Follows the JAR syllabus.

Recognised in the Oceanic Aviation Industry.

And also if I need to change from JAR to JAA what do I have to do and its financial implications?

You comments shall be highly appreciated.

Thank You
