Men's field hockey was introduced to the Olympic Games in London in 1908, with the 1924 Paris Games the only Olympics since not to include it in the programme. Women's hockey was introduced to the programme in Moscow in 1980.
New Zealand has only won one hockey medal at the Olympics, when the men's team won gold at the 1976 Games in Montreal.
The men's 2012 side, however, is a strong contender for a medal this year in London.
The team is New Zealand's most experienced men's hockey side in history, with Dean Couzins, Phil Burrows, Blair Hopping and Kyle Pontifex attending their third Olympics, and a further nine players competing in their second Games.
The Black Sticks men won the Sultan Azlan Shah Cup in Malaysia in June this year.
In late 2011, they were only narrowly beaten by the Netherlands in the Champions Trophy bronze medal match in Auckland.
The women's side, also known as the Black Sticks, also has a chance at a medal. They are currently ranked sixth in the world, but competition will be tough.
The team has some experience, with captain Kayla Sharland and Emily Naylor at their third Olympics, while Krystal Forgesson and Gemma Flynn will compete at their second Games.
