Labour Party leader David Shearer should be paying close attention to the current political landscape in Australia and the woes besetting his Labor counterpart, Australian Prime Minister Julia Gillard.
Ms Gillard's arch rival and predecessor as Prime Minister, Kevin Rudd, launched a push to reclaim the post he lost in 2010, resigning from his Minister for Foreign Affairs position and prompting Ms Gillard to call for a leadership ballot. Mr Rudd subsequently lost that vote by a comfortable margin.
The vote was the culmination of what has been a long period of destabilising in-fighting among the ranks of the Australian Labor Party.
No one is suggesting the same sort of rift exists in the New Zealand Labour Party.
Indeed, previous Labour leader Phil Goff made a measured and dignified exit post-election, a stark contrast to the way in which Ms Gillard deposed Mr Rudd in June 2010.
