Opponents of same-sex marriage are being slammed for distributing leaflets saying legalising the move will result in more incidences of AIDS and syphilis, and see the end of titles such as "husband and wife".
The leaflets were placed on cars in Auckland yesterday, including at AUT on the North Shore.
Labour MP Louisa Wall's Marriage Equality Bill is back before Parliament for its second reading tomorrow night.
Ms Wall says she would never deny any right for people to speak out and express their views.
But she is concerned leaflets such as this one promote information that's simply misleading and wrong.
