Unsurprisingly though, Chris Trotter has strong opinions on the whole affair which he has expressed in his weekly column. Via the Dom-Post and under the heading Labour shares Pike River guilt, Trotter opines:
It was a spark igniting lethal levels of methane gas that killed the 29 Pike River miners two years ago.
But, as the grim report of the Royal Commission on the Pike River Coal Mine Tragedy makes clear, the immediate cause of the disaster is of less interest than the manifold failures that allowed the spark and the gas to meet.
Other New Zealanders will write about the failure of Pike River Coal Company to adequately care for its employees' safety.
Much will be said about the bureaucratic failings of the Labour Department.
There will be critical scrutiny of the National Government's decision to disband the mines inspectorate.
But this column is written from the Left, so my focus will be on the party of the workers; the party whose founders came from the West Coast pits around Blackball; the party of the coalminers' trade unions; the party which for nine long years did nothing to prevent the tragedy which, in such a criminally deregulated environment, was only ever a matter of time.
Labour took control of New Zealand's state apparatus on November 27, 1999, and relinquished it on November 8, 2008.
During that time three Labour MPs held the labour portfolio: Margaret Wilson (1999-2004), Ruth Dyson (2005-07) and Trevor Mallard (2007-08).
All three of these politicians came into Parliament with strong Left-wing credentials.
And all of them, I'm sure, wanted to do only good things for the people they represented.
How, then, are we to explain their inaction? Their failure to impose a state-of-the-art health and safety regime on New Zealand's coalmining industry?
Trotter asks a very pertinent question here; Labour has nine years in office to clean up the mining industry, but seems to have chosen not to. And that is significant, as Chris Trotter notes:
Throughout the 19th century, the dangers facing workers underground and the disasters which so regularly took their lives provided a powerful moral impetus for labour movements all over the world – including New Zealand's.
In 2007, workers' safety campaigner Hazel Armstrong wrote: "The 1890s' West Coast coalfields have been evocatively described as a 'slough of despond'.
"They were notoriously hazardous working environments: 'There's always blood on the coal', miners said."
It's why the story of Paddy Webb's 1908 fight for the Blackball miners' rights became as ingrained as coal-dust in the political memory of Labour Party people.
How could three successive Labour ministers have forgotten so much?
The late Bruce Jesson offers a plausible explanation in his 1999 book Only Their Purpose Is Mad: "Somehow or other, the politicians ... had been persuaded that politics is an irrational and harmful activity.
"This followed from the firmly held Treasury belief that the marketplace is the source of rational behaviour ... It is assumed that politicians will always bring an irrational influence to bear on events, not just because they are irrational, but simply because they come from outside the marketplace."
This became an article of faith for the "Rogernomes" of the fourth Labour Government, and in spite of the many ideological and electoral challenges of the 1990s (not least from the Alliance and NZ First), it remained the core assumption of most members of Helen Clark's Cabinet.
There was no appetite in the Clark-led Labour Government for a return to the "heavy-handed" regulations of the past. As the source of rational behaviour, the market was still considered uniquely capable of regulating itself.
Tragically, it has taken the Pike River disaster to expose the fatal falsity of that belief.
Trotter is pretty severe on the Labour Party, but then again, that's nothing new. When Lange, Douglas et al took their Great Leap to the Right in 1984, it was the likes of Trotter and the cloth cap brigade that Labour alienated. The party's biggest issue now is how to once again win the heart of the working man or woman, so aptly described by Trotter as Waitakere Man.
But Trotter's final bite at Labour is the harshest; here's how he concludes:
Following the royal commission report's release, Labour leader David Shearer was asked if he thought the deregulatory pendulum had swung too far. He responded by saying that, "the Government needs to be much more hands-on than it has been".
It is to be hoped that these words reflect a genuine change of heart on Labour's part, and that the next time they're in office, Labour politicians will not hesitate to prevent the private sector's "drive for production" (and profits) from pushing workers' rights to effective workplace protection off the agenda.
Because if there's "blood on the coal" at Pike River, Labour helped to put it there.
