New Zealand Young Nationals
The Young Nationals, in conjunction with other New Zealand political party youth wings, support the current purchase age for alcohol of 18 years. They argue that the two biggest problems with the current law are the lack of emphasis on individual responsibility, and the ineffective attempts to enforce moderate drinking, and that raising the age, both at off-licences and at bars, will not solve the problem that New Zealand society faces around the issue of binge drinking. At the National Party Conference 2010 the Young Nationals passed a remit, led by 2010 National Policy Chair Edward Greig, for the continuation of a drinking age of 18.
Heuristic
For instance, in all states in the United States the legal drinking age for unsupervised persons is 21 years, because it is argued that people need to be mature enough to make decisions involving the risks of alcohol consumption. However, assuming people mature at different rates, the specific age of 21 would be too late for some and too early for others. In this case, the somewhat arbitrary deadline is used because it is impossible or impractical to tell whether an individual is sufficiently mature for society to trust them with that kind of responsibility. Some proposed changes, however, have included the completion of an alcohol education course rather than the attainment of 21 years of age as the criterion for legal alcohol possession. This would put youth alcohol policy more on a case-by-case basis and less on a heuristic one, since the completion of such a course would presumably be voluntary and not uniform across the population.
