David Cunliffe's presence is down to simple protocol that the leader of the Opposition be part of such delegations. Like Cunliffe, Pita Sharples, the remaining politician in the official party, was also vigorously opposed to the tour.
He has said that he will represent the protesters. But that sounds like an afterthought rather than an initiative.
If John Minto carries too much post-tour political baggage for National's liking or comfort, another option would have been to invite the now Paris-based Trevor Richards, who chaired the Halt All Racist Tours organisation before Minto's tenure.
Another possibility would have been Green MP Kevin Hague, who was arrested five times during the tour. But his presence would have risked being seen as National deliberately belittling Cunliffe.
Key has said the make-up of the delegation followed advice from the Ministry of Foreign Affairs.
But that ministry's officials are not paid to offer advice on domestic political gestures.
South African authorities stipulated heads of government would be able to take only one other member of their delegation into Johannesburg's Soccer City stadium where last night's memorial service for Mandela was being held.
Key opted for Cunliffe. That was the only option, however, if he was serious about reflecting Mandela's spirit of unity and national reconciliation.
