Another major exhibition at Wellington's $180 million convention centre has failed to break even, with the council refusing to say exactly how many people visited it.

Last July RNZ reported the first two major exhibitions at Tākina, Jurassic World by Brickman and Marvel: Earth's Mightiest Exhibition failed to either break even or reach their target visitor numbers.

The Doctor Who Worlds of Wonder ran from 1 June to 28 October and featured props from the BBC sci-fi show which first aired in 1963.
