Bryan Williams believes teams from the Pacific Islands should be considered for the Rugby Championships.
Williams was in attendance at Apia Stadium for the All Blacks' historic test with Samoa and he described the occasion as "one of the most special days in his life".
He played 38 tests and 75 matches for the All Blacks in the 1970s but he was also Samoa's head coach at the 1991 World Cup.
Samoa beat Wales and Argentina to finish second behind Australia in their group, which made the rugby world suddenly take sit up and notice of teams from the Pacific Islands.
His son Paul played for Samoa at the last World Cup and he said he could never understand why it had taken so long for New Zealand to play in Samoa.
