Speaker David Carter has ejected MPs from the House for the first time, kicking out Labour's Trevor Mallard and Chris Hipkins this afternoon.
Mr Mallard was told to leave the debating chamber after telling Mr Carter to "sit down 'til I'm finished" during question time.
Party whip Mr Hipkins was ejected immediately after attempting to repeat Mr Mallard's point of order.
The MPs had accused the Speaker of treating Prime Minister John Key more leniently than Opposition MPs.
They had been offended by Prime Minister John Key's statement that Government Communications Security Bureau director Ian Fletcher's brother was "way brighter" than Labour deputy leader Grant Robertson.
