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.
Alcohol laws of Wisconsin
The drinking age in Wisconsin is 21. Those under the legal drinking age may be served, possess, or consume alcohol if they are with a parent, legal guardian, or spouse who is of legal drinking age. Those age 18-20 may also be served, possess or consume alcohol if they are with a parent, legal guardian, or spouse who is of legal drinking age. 
Those age 18 to 20 may also possess (but not consume) alcohol as part of their employment.
