Treescape climber Dave Stejskal (number 6 in the NZ NTCC) has kindly sent through dates from Marlies for the 2010 TCC events - individual locations are yet to be confirmed.
Christchurch: 13 MarchAuckland: 20 March
Hamilton: 11 September
Wellington: 2 October
For out-of-Christchurch climbers it's probably a good idea to get your flights booked while the seats are still reasonably priced - the South Island TCCis being held the same week as the Ellerslie Flower Show which attracts plenty of people (to push up the price of the seats). JetStar is currently$69.00 Auckland-Christchurch one-way or $79.00 with up to 20kg of climbing kit.
