Just if it's any use, there are 2 shops in Christchurch that have a manitou shock service kit.
As I said above, Kris Olsen (Bike works) has a kit, and Bike Hq also has a kit.
Those are the only two tool kits in the south island as far as I know.
There's also another couple of tools that You'll need.
You'll also need a pair of 10mm shaft clamps to disassemble the damper shaft, and a floating piston removal tool. - have fun trying to remove the piston without the tool, it won't be easy.
