The Black Caps vs Australia in the Twenty20 format is almost as rare as a Wallabies victory at Eden Park…or a New Zealand win at the SCG.
The Black Caps have played 106 Twenty20 internationals since their maiden match in the shortened format in 2005 - but just six have been against Australia. Compare that with 18 clashes against departing tourists Pakistan and 15 both vs South Africa and Sri Lanka.
Just six Twenty20s - and only two of those were New Zealand wins. Over the same time they've played 44 ODIs and 14 tests.
The two square off on Saturday at the Sydney Cricket Ground in the first match of the Tri Series, which also includes England, and it's fair to say the clash is an irregular occurrence.

They're the neighbours that might share a nod while putting out the rubbish once a week but won't be standing around the BBQ each summer.
It all started out so well. February 17, 2005 at Eden Park was the maiden international match in the 20-over format for both teams. The transtasman rivals played five times between 2005 and 2010, with Australia winning the first four matches followed by a remarkable tie and eliminator win for New Zealand at the now defunct AMI Stadium.
That was the last Twenty20 international, outside of tournament play, between the two sides. A match played in pre-earthquake Christchurch in which Steve Smith was a leg-spinner batting seven.

The most recent clash was in in Dharamsala at the 2016 World T20 where the Black Caps beat Australia by eight runs in a pool match.
This weekend's game will be just the third time the Black Caps will play a T20 clash on Australian soil. They played a one-off Twenty20 at the end of the 2008-09 tour, also at the SCG. Australia won a close match by just one run, but that was after Nathan McCullum hit a six off the last ball with the game out of reach.
It's also been a long time between celebratory drinks in coloured clothing for the Black Caps on Australian soil. New Zealand have never won a Twenty20 game in Australia and their last ODI victory was in 2009.
At the SCG the Black Caps have six wins in 22 ODIs, the last being in 2002.
