Wanted: Billet for German Judoka

If you can respond to the following please contact Rick Littlewood.
. . .
Dear sir or madam,
I am Moritz Heibrock from Germany. I am sixteen years old and practising judo since I am six. At the moment I have the blue belt (2nd Kyu) and if everything works, I will have the brown one in April. Here in Germany I train four times a week and at some weekends I am taking part at competitions. My weight is 80 kg and I am 1.90 m tall.
I am planning to go to Auckland as an international student from August to December and I want to practice judo during that time too.
I had a look at your homepage and saw that there are four trainings (Mon, Wed & Fri from 6 to 7.30 pm. Sat 12 (noon) to 2 pm) per week.
Do you think I could take part at these trainings and would they be suitable for me? Would there be suitable partners in regard of technical skills and stature?
What would it cost?
I would be very happy, if your club could offer an opportunity for me to go an with judo during my stay in Auckland and if I could make friends among the judoka of New Zeeland!

With best regards

Moritz Heibrock
