Hi Robin, I have serious doubts that NZ harness is booming - in fact it may be the opposite.
While this forum was once a very strong NZ forum - it no longer is, despite Harnesslink being NZ owned.
The exodus happened about 15yrs ago, pretty much before my time.
There is another NZ forum where you will find more NZers - Harness Cafe
https://www.racecafe.co.nz/forums/in...-harness-cafe/
It should be remembered that NZ is pretty much the size of Victoria, Australia - which until very recently was considered Australia's strongest harness state, now due to mismanagement some would argue that it is 4th. NSW is the strongest and at best Vic is in a battle for 2nd with WA and QLD. Vic's prizemoney has not kept up for a decade due to budget problems and is getting worse.
ps You might notice that nobody has made a post here for a few years, which is why I made a NZ thread on the Australia board
