Hello,
am out in NZ at the moment, been out here a while now. Thought i could offer some advice r.e the girlfriend issue. Anyone is allowed to bring girlfriends/partners out and a couple have done, although the accomodation is out of town and is basically an en suite room plus fridge and microwave. You also have to appreciate Hamilton is not the most happening of places. Also, CTC will only issue one magnetic key card per room. Spouses/girlfriends would definately need a car of thier own. The course is quite intensive and engaging, i would suggest unless the partner had an engaging job here it would be unlikely that they would last the course of the stay. In addition, and on top of delays to the flying schedule, rumours would suggest that in future, the CPL and IR might be done here as opposed to bournemouth so you may be here longer than planned. Hope this helps.
Good luck to anybody doing selection.
