They say nothing will keep an Englishman from his pint. In Britain, the Weights and Measures Act - summarised on British pub walls - ensures when you order a pint of warm bitter you get a pint of warm bitter.
The Aussies and the Irish are sticklers on that point too. Both countries use metrics but have laws to ensure drinkers get what they order.
So when rugby fans arrive here, they will expect to get what they order - a pint, or 568 millilitres for those brought up on metric measures.
But New Zealand law bans the sale of any food or drink using imperial measures, so it's illegal to advertise a "pint" of beer for sale. If a drinker asks for a pint, it's legal to serve it - but it must be the full 568ml or the publican can be fined as much as $5000.
Confused? So are pubs, apparently. A snap survey of a few Auckland licensed premises showed that none were complying with the law. One of the city's top hotels, the Langham, served a 370ml glass of beer when asked for a pint. The $10 "pint" of Monteith's Original arrived in a goblet-shaped glass.
