Trevor Richards, Tom Newnham, John Minto, Dave Wickham and others formed HART in 1969 to protest against the proposed 1970 New Zealand tour of South Africa.
In 1973, HART promised a campaign of civil disruption if the Springboks, the South Africa national team, toured New Zealand.
Newly elected National Prime Minister Rob Muldoon refused to cancel the tour, which went ahead.
Subsequently Commonwealth leaders adopted the Gleneagles Agreement whereby they agreed to discourage sporting contact with South Africa.
HART's reason for existence ended when South Africa rescinded the Population Registration Act, 1950 in 1991, leading to the further dismantling of apartheid by 1993.
