Sir Michael Cullen is expecting to face a bit of ribbing from his former Labour Party colleagues today - he was, after all, Deputy Prime Minister in the Government that abolished the very knighthoods he has now accepted.
But Sir Michael is unrepentant about becoming a Knight Companion of the New Zealand Order of Merit with its accompanying title of Sir, saying he is "very chuffed".
"Bluntly, I wasn't the most enthusiastic supporter of what we did. I wasn't surprised that the public strongly supported the reinstatement of the knighthoods in 2009."
While he had once been "misinterpreted" as pro-republican, he was a traditionalist and believed that with the attention on Prince William and Kate Middleton, support for the monarchy was probably at a high level in New Zealand. He would like to see some consensus about an honours system that was more specific to New Zealand, but had no ideas on how that could be achieved.
When asked whether he expected disapproval from former Prime Minister Helen Clark, who abolished the knighthoods in 2000, he laughed and said, "Not to my face".
