This new character has dazzled the cricketing world while providing the perfect platform for this country's co-hosting of the World Cup. International commentators have noted that New Zealand embraced the event far more than Australia.
This meant large crowds even for pool matches that did not feature the Black Caps. Those crowds have been treated to outstanding cricket on very good pitches, none more so than those who have gone to Eden Park.
Who would not be enraptured watching the Black Caps' nail-biting victory over Australia, Pakistan's upset victory over South Africa, Zimbabwe's unsettling of India, or, most stunningly, New Zealand's semifinal victory over the Proteas?
The Black Caps' aggressive approach has also played a significant role in salvaging the 50-over game. The success of Twenty20 cricket had led many to conclude that the longer limited-overs game had little future. Games such as New Zealand's semifinal victory have occasioned a revising of that view.
Indeed, based on the crowds at this season's domestic Twenty20 games, that format may be in the greater difficulty. The 50-over version has the advantage of being long enough to allow major fluctuations in fortune, a possibility largely alien to Twenty20 cricket.
Not that any of this will be concerning the Black Caps as they prepare for this country's first appearance in a World Cup final.
It has been a long time coming. On six occasions, New Zealand teams have reached the semifinals, only to be caught out by a lack of self-belief. That is not a trait of a unit in which players are encouraged to have confidence in themselves and their teammates. This has laid the foundation for a team that, like all the best ones, seems almost always to find a way to win.
Tomorrow, it faces the ultimate challenge. The Australians are well acquainted with World Cup finals, and have the obvious advantage of playing at a ground they know well. They are the bookmakers' favourite.
This, however, is a Black Caps team that since the start of this astounding World Cup has made a mockery of the odds.
