Recently, Mental Health Foundation proclaimed that equality in marriage can play important role in improving the mental health of the New Zealanders. With the aim of encouraging better mental health, the Mental Health Foundation (MHF) has even showed support to the changes in the Marriage (Definition of Marriage) Amendment Bill.

The Chief Executive of MHF, Judi Clements said, "Sexual and gender minorities experience significantly poorer mental health than other New Zealanders". It is hoped that the changes thus proposed in Marriage Bill will bring significant changes in the mental health and wellbeing of the New Zealanders.

The minorities in New Zealand often become the victim of depression, anxiety, suicidality and of substance abuse. According to the discrimination law of New Zealand, the minorities are not acceptable and therefore fewer rights are given to them.

It has been found that gay men are happier in legal marriage as compared to those who are not allowed to get married or even seen together in the public. If the proposed changes in the bill are made then new values and respect will be set for the society and citizens. Same-sex couples are not getting the respect they want. But, it is hoped that in the coming time, they will be respected by the society.
