Well I dont know about New Zealand, but the UK economy will probably start recovering sometime during 2010.
The airline industry will lag behind the economy, and probably wont start recovering until 2012 - 2013, as for recruitment of low hour pilots, I cant see this starting until 2015 onwards.
So id look to be starting your training during 2014 - 2015.
This is my opinion, I hope im wrong, but I fear I wont be.
