In 1967 protestors laid a protest wreath in Christchurch on Anzac Day to highlight their opposition to the Vietnam War. They were subsequently convicted of disorderly behaviour. A decade later further controversy arose when a women's group laid a wreath in memory of women killed and raped in war. During the 1980s other activist groups – feminists, gays, Māori and peace activists – all used Anzac Day services to seek publicity for their cause. Some ex-servicemen and politicians also used Anzac Day ceremonies to speak out during the anti-nuclear debate of the 1980s.
