Again, if it is him (I can't see there being another Car care franchise in Tauranga) I hope it's because their music business has taken off and not because they are coming back to the UK. I know they were struggling financially when the book was written.

I would definitely recommend the book ("A new life in New Zealand". Paul Goddard) for anyone thinking of going out there as it gives a good account of the emotional side of relocating to the other side of the world. Which I suppose you can get from these forums ;)
Note: there's not much technical stuff about moving in the book.
