Bay Flight in Tauranga is my favourite school in NZ. Nice airfield, nice training environment, high instructing standards, CFI is a really decent guy, and what an absolutely fantastic city to live in while you're training
(Yes, I used to instruct there. No, I don't get any kickbacks from recommending it ... I do honestly think it's a great little school, and I love the city so much I just bought a house there :-).
