The Maori Party polled a dismal third in a byelection arising from the death of Labour's popular Parekura Horomia, and John Banks lost his ministerial warrant when he was committed for trial on charges arising from the "anonymous" Dotcom contribution to his 2010 Auckland mayoral campaign.
By that time, the 2013 mayoral campaign had produced the year's greatest scandal. Two days after Len Brown's re-election, Aucklanders learned their high-minded mayor had been having an extramarital affair for two years.
Sadly for Mr Brown, his beau, Bevan Chuang, also gave her heart to a rival campaign worker, Luigi Wewege. Some found his conduct equally distasteful, but advisedly the mayor blamed nobody else.
Labour, the party that backed Mr Brown, was doing better in national politics. David Shearer gave up the leadership days after flourishing two dead snapper in Parliament, an act that prompted Ms Collins to quip, "Which of those three will last longest?"
Three Labour MPs vied for the leadership under new rules giving the wider membership and affiliated unions more votes than the parliamentary team. David Cunliffe won a well-conducted contest that gave Labour good publicity and a lift in the polls.
Labour and the Greens together edged ahead of National in some surveys, but not all.
The Government comes to the end of its fifth year still the preferred party by a large margin, but probably in need of new partners next year. Conservative Colin Craig could be helped into a seat if he is more sensible than some of his recent comments. A new party of market liberalism might emerge from Act. Expect the unexpected in a new year.
