I came to New Zealand to do my PPL bit cheaper than the Uk but it was more like you say for some life experience and have a change of scenery. only had 3 days of light rain in 2 months but saying that it has Pi**ed it down for about a week now so no flying. Hard work doing all the exams quickly id reckon, but many people do it here or in the USA and spend 3-4 weeks to get there PPL, but if like me you can have longer, 2-3 months then do as it will be far more enjoyable without the stress of time! Flights are obviously a bit cheaper to the US but you have to bonus of no Americans here
