Weights and Measures Act
Intent of the Act
To make sure customers get what they pay for, and businesses sell correct quantities.
Your rights under the Weights and Measures Act
Goods sold by weight, volume, length, or number must be:
- accurately weighed, measured, or counted
- clearly labelled with the correct net quantity — this means the product itself, not product plus packaging.
Equipment and processes used to weigh or measure goods must be accurate. The Act also specifies which measuring units, e.g. kilogram, metre, millilitre, must be used for certain types of goods.
When the Weights and Measures Act applies
Businesses that sell, make, process, pack or import goods to be sold by quantity. Examples include:
- coffee beans by kilo
- firewood by cubic metre
- potting mix by litre
- railway sleepers by number.
When things go wrong
If you can't resolve it with the retailer, you can make a complaint to Trading Standards. It can inspect weighing and measuring equipment in response to a suspected problem. You might also think about taking a case to the Disputes Tribunal or district court.
