Maori are one of the two peoples that make up New Zealand (Maori and Pakeha). Maori as an individual people have every right to represent themselves in any field of endeavour that they choose including Rugby. This right is enshrined in New Zealand's founding document, the Treaty of Waitangi. The Maori rugby team has as much right to exist as any other representative team.
To be a selected as a member of the New Zealand Maori rugby team you must be Maori or a descendant of Maori and identify yourself as Maori.

Rugby in Maori is "whutupaoro," derived from the English word. Rugby is a popular sport in New Zealand, and Maori culture has strong connections to the game through the New Zealand All Blacks national team.
No, the All Blacks are selected from all New Zealander players. The New Zealand Maori representative side is selected from Maori players.
Oh yes, you are unlikely to see an All Black rugby team without one ! (The National Rugby team of New Zealand are the All Blacks, and very good rugby players they are, as good as any.) Before the match the All Blacks perform the Haka, a Moari war dance.

The Maoris are the native people of New Zealand, and a kainga is the Maori word for home. I'm not sure if the word (possibly with the extra 'a' on the end) also has another meaning - perhaps something related to the haka which the All Blacks rugby team are famous for chanting.

The nickname for the Scotland rugby team is the "Scots" or "Scottish Thistles."
The Haka is a form of cultural expression exclusive to the Maori of New Zealand. The haka that is most familiar to pakeha (non-Maori), the haka most likely to be performed by international sports teams such as the All Blacks, is Te Rauparaha's Haka, also known as 'Ka Mate! Ka Mate!'
There are 13 players on a Rugby league team compared to 15 on a rugby union team.
