Hmmm, Golden Wings.
Well if you have pots of gold. The UK pound does go much further in NZ but it is still only in the order of $2.50 for each one of them.
Do Golden Wings have a realistic trainer for PPL other than the new Seminole and King Air 350 ?
Nelson is a nice place and has good winter weather for flying. He is going to need to fly basically every day but NZ is good for that anyway.
Many clubs would love to have the business, and Nelson and even Blenheim would be good.
The Marlborough Aero Club have just refurbished one of their Tomahawks and may have even finished the second by now.

Well worth an email I would have though.
You may be in for a pleasant surprise..
