The first New Zealand title to find its way to laserdisc would appear to be 'Merry Christmas Mr Lawrence'. The earliest known New Zealand title to be transfered to dvd is the 1998 release of 'The Piano'.
Since there are arguments about whether 'The Piano' is a NZ production, some state that the first all-New Zealand DVD title is Peter Jackson's 'Braindead', which first appeared September 1998.
As of 06 September 2021, there are at least 302, non-documentary, feature films on dvd that most people would consider New Zealand titles. Valid arguments could be made for adding and removing titles
from such lists, including the ones found here. However in the end, all such lists are subjective. IMDB (International Movie Datebase) ratings with a (?) after them are questionable due to their small number of votes.
