I don't think I've heard of just a NZ series, but Auckland and Wellington-Hutt Valley teams play each other in the Australasian Gaelic Games alongside all the Australian state sides. Last year they were hosted in Auckland and I think Welly-Hutt kicked our asses, as did all the Aussie sides.

(I was invited to try out for the Auckland side, but I was third-choice keeper behind a local star and a chick who'd played county level in Ireland so I didn't try very hard.)
