I think a case could be made for John Dawes's 1971 British Lions as the greatest sporting team ever to visit the land of the long white cloud. The only time a Lions touring side has ever bested the ABs in 100 years of tours.
They were based around the magnificent Welsh side of the 70s, with a set of backs that must be close to being unparalleled. The names still have resonance today: Gareth Edwards, Barry John, JPR Williams, Gerald Davies & John Dawes. Add England's David Duckham & Ireland's Mike Gibson to the mix & that is a seriously good backline.
It's very tricky to compare across sports & years, but with all respect to the recently completed series between The Black Caps & the Aussies I doubt it will be remembered so vividly.
Of course other factors have to be considered, not least the rarity of Lions tours & the comparative surfeit of cricket tests nowadays, but, rightly or wrongly, the All Blacks are still considered the gold-standard in Union. Ironically this is in part due to The Lions scant success down there; when the Springboks have played the ABs they have historically had the edge in terms of results, but because the Lions have beaten them with more regularity (well 4 times) the perception in the NH is that the ABs are the bigger ask.
This may've been better posted in OT, but hard not to mention Union when talking about sporting teams in NZ!
