Every 4 years each of the 192 member country’s of the United Nations are examined under a system called the the Universal Periodic Review. The review rigorously looks at many of society operations in light of the 1946 post WW2 agreement on Human Rights. It also gives the opportunities for U.N. members and NGO’s to comment in an open forum about the findings in the report. Take a look at New Zealand report here which was released recently, also look at the governments formal response to the report here. For more info on the UPR system have a look at this wiki
