Strategy toward metrication

The New Zealand metric symbol was introduced in March 1971. To give metrication a human face, a baby girl whose parents agreed to co-operate was nicknamed Miss Metric. News and pictures of her progress were intermingled with press releases about the progress of metrication. By the end of 1972 the temperature scale, road signs, and measures used in the sale of such items as

Exceptions

Although New Zealand completed metrication in the 1970s, a 1992 study of university students found that at that time there was a continued use of imperial units for birth weight and human height alongside metric units. On the 30th anniversary of the introduction of the metric system in December 2006, the New Zealand Consumer Affairs Minister,

, commented that "Now 30 years on the metric system is part of our daily lives" but noted some continuing use of imperial measurements in some birth announcements of baby weights and also with people's heights. A few uses of imperial measurements remain, mostly to do with interoperability: * The aviation industry is one of the last major users of the imperial system: altitude and airport elevation are measured in feet. All other aspects (fuel quantity, aircraft weight, runway length, etc.) use metric. * Where exact fitting of parts is required, such as between nuts and bolts, or between tyres and wheel rims. * Since the late 1990's, display sizes for screens on televisions, computer monitors, tablets and mobile phones have reverted to having their
