New Zealand introduced the metric system on 15 December 1976.<ref>{{cite web| url = https://www.beehive.govt.nz/release/30-years-metric-system| title = "30 Years of the Metric System"| access-date = 4 February 2021| archive-date = 9 February 2021| archive-url = https://web.archive.org/web/20210209075115/https://www.beehive.govt.nz/release/30-years-metric-system| url-status = live}}</ref> Aviation was exempt, with altitude and airport elevation continuing to be measured in feet whilst navigation is done in [[nautical mile]]s; all other aspects (fuel quantity, aircraft weight, runway length, etc.) use metric units.

Screen sizes for devices such as televisions, monitors and phones, and wheel rim sizes for vehicles, are stated in inches, as is the convention in the rest of the world - and a 1992 study found a continued use of imperial units for birth weight and human height alongside metric units.<ref>[http://www.psychology.org.nz/cms_show_download.php?id=785 "Human use of metric measures of length"] {{webarchive |url=https://web.archive.org/web/20130209034410/http://www.psychology.org.nz/cms_show_download.php?id=785 |date=9 February 2013 }}.
