Whakakī i te rerenga e whai ake nei: Ko te Rōpū Ono (G6) he huinga tūmatanui i huihui ai ngā kaiārahi o ngā whenua whai rawa rawa: France, Germany, Italy, Japan, United Kingdom me te United States i te tīmatanga o te tau 1976. Ko te Rōpū o te Whitu (G7), i hui mo te wā tuatahi i te tau 1979, i hangaia ki te tāpiri o Kanata. Nō reira, i whakatūria ai te Rōpū o te Tekau (G8), i hui ai mō te wā tuatahi i te tau 1997, me te tāpiri o Rūhia. I tua atu, kua whakauruhia te Perehitini o te Komihana o Europi ki nga hui mai i te tau 1981. Kāore ngā hui i whakaarohia kia honoa ki ngā rōpū nui ake o te ao; ā, ko te mea pono, he whakakeke ngawari ki te āhua o ētahi atu hui o te ao, he wāhanga o te tīmatanga o te mahi tahi i waenganui i te Perehitini o Wīwī, a Giscard d'Estaing, me te Kaihautū o Tiamana ki te Uru, a Helmut Schmidt, i a rāua e whakaaro ana i te hui.
