The defence is often used in court by defendants to justify violent attacks if provoked by a victim.
But now Mr Chauvel has drafted a bill to get the defence of provocation removed.
It was an "aspect of our criminal law which provides justification for lashing out and violence against people," he told the GayNZ.com website.
The partial defence of provocation "lets people know they can get away with murder, and it's time we did away with the provision."
He claimed there was strong support for the move and said the current "provision is a travesty."
The Law Commission released a report in 2007 which said the partial defence of provocation should be abolished.
The recommended changes to the Crimes Act 1991 would allow such factors to be weighed in as aggravating and mitigating factors during sentencing rather than in setting the charge.
The report said the defence was originally used to avoid the mandatory life sentence for murder. However, under the Sentencing Act 2002, a life sentence is no longer mandatory.
The report said the partial defence of provocation is "irretrievably flawed" because it claims to be a partial excuse, assumes there can be a loss of self-control, and that in extreme circumstances an ordinary person, when provoked, will resort to homicidal violence.
