Auckland and Canterbury had a great rugby league rivalry in the 80's and 90's but that has ebbed as the NRL overtakes the focus and the Warriors hog the headlines.
The national soccer league brought tremendous duels in the 70s between Mt Wellington, Blockhouse Bay and Eastern Suburbs however that league could not be sustained.
It was much the same with softball when neighbours Hutt Valley and Wellington slugged it out at the inter-provincials in the late 80's. It seems extraordinary that micro-area sprouted into a national rivalry.
Some tournaments return like the Plunket Shield which used to be a significant sporting event on black and white TV screens in the 60's and 69 massive on black and was reconstituted (not in black and white) in late 2009.
Athletics found a golden seam in the late 50's and 60's with the middle and long-distance excellence of Peter Snell, John Davies, Murray Halberg, Bill Baillie, Barry Magee and Marise Chamberlain.
Nick Willis is front and centre now on the track while the nation's focus is spread through a range of other events and sports.
