It got windy in Wellington on Wednesday. Nationals MP Tau Henare sledged Labour frontbencher Trevor Mallard on the floor of parliament about his personal relationships. Mallard invited Henare to step outside. The rest, as they say in the classics, is history. Though not, sadly, quite history in the Aaron Burr-Alexander Hamilton class.

Report (one of many) on the TVNZ website, plus parliamentary video. The contretemps took place off-stage, but Henare does show us his bruise.
