Taupo Air Services,
A long established training, charter organisation located in the heart of the north island. They have a varied fleet (cub, 172, 206 etc) and the cp has the experience/knowledge/personality to make your flying safe and enjoyable. - I also think you'll find the price to be very competitive and you will probably be one of their only students so no waiting!!!
besides that she's a beautiful location with lots of interesting stuff to do whilst not flying, (skiing, sailing, tramping etc).
wish I was back there meself now
