Yep the one at Wigram owned by the CFI at Chch flying school, he is a very good instructor, go speak to those guys. Pm for more info. (got my PA.18 rating, but only 100hp model, it is not a PA.18-150 rating..)
You missed out on a good opportunity for tailwheel training, a chap used to hire his Maule (ZK-SLS) out to the flying school there, he has recently sold it to the north island, great machine, was priviledged to have done a few hours in it (quite a well known Maule), but that Cub is still available, your best shot in the area I believe.
