There will be few secrets and no need for reintroductions on Friday when Australia and New Zealand enter Dharamsala's HPCA Stadium.
The trans-Tasman rivals have played a stack of cricket against each other this past summer, squaring off in five Tests and three ODIs.
Earlier in 2015, there was the one-day World Cup final at the MCG and a thrilling pool match at Auckland's Eden Park.
Throw in the bonds established during the Indian Premier League (IPL) and there is a sense of familiarity about the teams' opening World Twenty20 clash.
"We don't need to have a team meeting, that's for sure," allrounder Mitch Marsh joked.
"We've obviously played against them a lot.
"There's a few new players to come into their T20 side so we'll have a look at them.
"Every game is important but to start your tournament off on a winning note against a very good Kiwi side is going to be extremely important."
The loser of the match will find it hard to progress beyond the group stage, given only the top two advance and they share a pool with India, Pakistan and Bangladesh.
Previously, those sort of stakes might have brought out the worst in both sides.
Now it's very much a friendly rivalry, with Josh Hazlewood suggesting NZ's recent charm offensive has proven somewhat infectious.
"A little bit has rubbed off. Having played them so much in the last couple of months, you look at the way they go about things," Hazlewood told AAP.
"That's the same with most teams. After the series, you have a beer, you have a chat and have a laugh.
"It's probably where you learn most of your stuff about the other team, really.
"The Kiwis are a great bunch of blokes."
The IPL has also had a positive impact on relations according to many players, including Kiwi paceman Tim Southee.
"It's a chance to get to know them," Southee said last year.
"A lot of players are completely different to how they come across on the field.
"He (Shane Watson) is the complete opposite to what I actually thought he was.
"We had a few run-ins in previous years.
"But he's a bloody good bloke ... a gentleman."
