It was a very discussed tour, due the fact that South African authorities, imposed the exclusion of Maori's people from the team. This racist politics created a lot of controversial in New Zealand.
New Zealand Rugby union then refused any other tour for the successive 10 years until Maori players participation will be accepted in 1970. In that occasion South African authorities, gave them the ridiculous definition of "Honorary Withes", but controversies reimained. In 1976, all the African countries boycotted Olympic Games contesting the All Blacks' tour of South Africa.
Then, the 1981 Springboks' tour, will be contested by a large part of New Zealand public opinion, with riots and demonstrative actions.
In 1985 public opinion convinced NZRU to cancel another tour in South Africa. Only with the end of apartheid, in 1992 al this controversy had a finish.
Also outside the political troubles, the results of the tour wasn't good in any case for All Blacks, that lost the series with only a victory and a draw on 4 match against the Springboks
