One Hundred Crowded Years is a 1940 New Zealand historical documentary film. It was produced by the government film studios at Miramar for the centenary of New Zealand. Cinemas agreed to air the film without charge to the government, and to donate the sixpence fee from children to "patriotic funds". About 8,000 schoolchildren in Wellington saw the film, raising £200 for those funds. However, not all showings were well-attended. One showing was cancelled because the local body did not allow screenings on Sundays. Another local council rescinded its ban on Sunday screenings to allow this film to be shown.
