In New Zealand a ‘Standard Drink’ is one that contains 10 grams (about 12.5ml) of alcohol. The standard drinks measure is a simple way for you to work out how much alcohol you are drinking.
All beverages are labelled with their per cent alcohol by volume (i.e. 5%), and the number of standard drinks in the container. (i.e. 1.3 standard drinks). It is important to note that drink serving sizes are often more than one standard drink.
