Have you looked at this page?
There are some mistakes - old, outdated info in a few places but it gives a general picture of the clubs operating now.
Most of the action is in Auckland, some in Wellington, not much here in Hawke's Bay, almost none in Taupo and only in specific spots down south (like Cardrona or Lyttelton), unless you're looking for a Morris side.
There sre local sessions like the one on Tuesday nights here in Hastings but they're usually informal and not included in this list.
