About $5000 NZ I think...which is about £1650 ish, depending on exchange rate movements... in 1993 and 56 hours (legal minimum is 50 in NZ).
Think about it - it would probably be cheaper to fly to NZ and stay there for say 6 weeks to complete PPL from ab initio than to do it in the UK provided you picked your venue and accomodation with some care...
And the terrain around which you would learn would almost certainly be more interesting than say the south of England.
And you could do it during the European winter ie NZ summer, thereby also slipping out of those 3.45pm sunsets...
