Roopu or Rōpū is a Māori word for an organisation, group, or collective. The term is widely used throughout New Zealand as part of the name of organisations, especially those which have a strong connection with the New Zealand Māori population. In organisational names, it is usually prefixed with the word Te ("The"). Traditionally, the word is spelt roopu, but modern linguistics favours the use of a macron over a single vowel to indicate a longher sound, rather than a double letter. The word is likely to be a Maorified form of the English word "group".
