Well there was the Wellington test, the All Golds match, the tour to GB, there were more players added to the hall of fame and there was a huge book published on the history of the Kiwis. Probably there were a few other events I don't know about.
The NZRL's perilous financial state would have made it impossible to have any larger events, and it's not like there's a century old national comp over here like the NRL to have events during.
