Looking for a trekking partner (19 Nov. - 17 Dec.)

Hi everyone, my name is Nick, I'm 28 years old German living and working in Prague. This is my first trip to this country and I'm especially interested in two things: trekking as much tracks as possible in this beautiful country and having a good time while meeting new people. I'm arriving at Auckland on November, 19th, and I'm gonna stay in New Zealand till December the 17th. Is there anyone, who wants to meet up somewhere and getting on the track with me? First, I'll go the the Tongario Northern Circuit on the Northern Island. Then, I'm heading directly to the Southern Island, having such trips in mind as the Abel Tasman coast Track, the Travers-Sabine Circuit, Banks Peninsula Track and a trip on the stuart-island (no chance that I'll make all the trips I would love to make ... but this is a well-known problem of every holiday in NZ, isn't it?). I have no definite plan yet and thus I'm flexible and really open for other suggestions. See you in New Zealand, Nick
