Travelling to Rotorua from the UK and getting a boat


I'm a UK paddler, just got onto a 23-month Working Holiday visa and I'm planning to head over in September. Looking to spend the first half of the visa in Rotorua- what's my best bet for getting over there and getting hold of a good river runner/creeker? I've got all my own kit, but I figure it'll be more faff than it's worth to bring my Raptor with me.
