Description The New Zealand national baseball team, also known as the Diamondblacks, is the representative team at the international level for New Zealand. The team is controlled by Baseball New Zealand, the country's governing body. The team competes in the Oceania Championship, where, in 2007, it withdrew from play, giving Australia an automatic berth into the Final qualification tournament for the 2008 Olympics. The "Diamondblacks" nickname is one of many national team nicknames related to the All Blacks.
