There are quite a few Gazelles around. The MK1 version was made in Christchurch, and then the molds were moved to Wellington and the Mk 2 version was made here.
Several are raced at my club (Evans Bay) they go quite well, but I think the extra weight means they struggle a little to hold off the Noelex 25's.
A strong capable cruiser, I have a book written by a retired couple who circumnavigated NZ in a Gazelle. The North Island over one summer and the South Island another summer. The book is rather laborious reading, called "Starlight around New Zealand". They chose the Gazelle for the trip
