Labour leader Andrew Little said the case could be made for McCaw, 35, to get the highest honour in the land and made a member of the Order of New Zealand. That is limited to 20 living New Zealanders at any time and there are currently 18 ordinary members, leaving two places open.
"I think given the scale of his achievements and what he has come to represent, it would be more fitting for him to be considered for membership of the Order of New Zealand."
Mr Little said it was to recognise unique and special contributions to New Zealand and if it existed when Sir Edmund Hillary climbed Everest it was likely he would have been appointed a member of the ONZ then.
"[McCaw] is known worldwide, not only for sporting achievements but as a leader and an ambassador for New Zealand and I think he fits the criteria."
Dame Susan Devoy also spoke about the issue in 2011, saying in general she did not believe people should be given such honours solely for sporting achievements. However, she expected one of the All Blacks would be honoured "and Sir Richie's got a nice ring to it, doesn't it?"
