There is indeed a very strong vintage karting movement in NZ. There have been a number of races for vintage karts run in conjunction with other meetings (eg the Blossom Festival meetings since about 2008), Taranaki Gold Star, Hamilton a few weeks ago etc.
In March 2015 there was the first ever NZ Vintage kart GP meeting held at Hastings which attracted some Aussie competitors. The Australians won the Trans Tasman challenge, not through their prowess on the track but by winning the pie eating/beer drinking race.
There is a "Facebook" page and a vintage section at www.kartsport.org.nz At last count there were about 130 vintage karts registered.
