Hamilton is an extremely busy airport. CTC make up quite a large proportion of movements, but there's also a couple of other flying clubs, several Air New Zealand shuttle flights a day and the occasional military aircraft. I've even seen a 737 doing (very large) circuits there. It can end up being quite difficult to actually fly in the circuit at Hamilton!
Because of this, CTC elected to send me and 8 others from my course on a 4-day "flyaway" to Whakatane, which is a quiet uncontrolled airfield on the east coast. By the time we went, I'd completed 5 flights - basically covering climbing, descending and turning. By the end of the week I'd have completed 9 more flights, including my first solo and a whole bunch of solo circuits.
