What is "helengrad"

Helengrad was a satirical or pejorative neologism in New Zealand politics applied to New Zealand's capital city Wellington. However, it was sometimes used by the Labour party's opponents (including the centre-right National Party) and critics to describe New Zealand as a whole and occasionally the fifth Labour government itself. In January 2008, the term 'Helengrad', "a noun used to describe the iron grip of New Zealand's prime minister over Wellington", was reported as having made Australia's Macquarie online dictionary among 85 other new words.
