General quantity labelling requirements

Goods sold by weight, measure or number must have their quantity marked or labelled using one of the units of the metric system.

Labelling requirements

All packaged goods sold by quantity must comply with the following labelling/marking requirements:

  • Units of the metric system must be used when marking net weight or measure, as follows:
    • Net weight: kilograms, grams or milligrams.
    • Liquid measure: litres, decilitres, centilitres or millilitres.
    • Measures of length: metres, centimetres or millimetres.
  • Only one unit of weight or measure must be used.
  • Decimals must be used for part units — that is, 1.5 L not 1½ L.
  • The marking of net weight or measure must be:
    • in a prominent position
    • in close proximity to the name or description of the goods (if applicable)
    • clearly written or printed in letters and figures at least 2 mm in height, and
    • in a colour that contrasts distinctly with the background.

Notice Icon Blue3 NOTE

If, due to the size of the goods or package, it's not possible to use letters and figures of at least 2 mm, the marking may be in smaller letters and figures. These should still be large enough to be clear and legible.

Examples

The marking must be in the form of one of the following examples:

Non-metric units of quantity

You can only use a non-metric unit of weight or measure when marking goods if:

  • it's additional to, and not given greater prominence than, the metric marking, and
  • either:
    • the goods have been imported into New Zealand, or
    • the goods are part of a line that is intended for retail sale in New Zealand and another country, and the law within that other country requires them to be marked with a non-metric unit.
