region. In a joint partnership between the two teams, the NZRL and NRL, all money raised from the match was divided between the Pike River mining relief fund and the West Coast Rugby League. The teams arrived on 3 February 2011 to carry out community appearances in the region. The Crusaders also announced that they would play their first home match of the 2011 Super Rugby season in the West Coast Rugby Union jersey. These were later auctioned off to raise money for the Pike River mining relief fund. On 17 March 2011, after attending a national memorial service for the earthquake in Christchurch, Prince William visited Greymouth and met families affected by the disaster. On 27 June 2011, The Australian featured an article titled "Miners doomed by fatal flaws" which alleged that Peter Whittall had not ensured the Pike River Mine had installed safety measures which are common in Australia, but are not legally required in New Zealand. The possible safety measures not used in the Pike River Mine were a "tube bundle" gas monitoring system, stocks of food and water, breathing apparatus, and a second escape route. Whittall has consistently maintained that safety standards were high. A former mine supervisor alleged that miners continued to work when the methane gas concentrations exceeded the threshold of 2%. It is also alleged that the miners routinely blew compressed air over the methane alarms to prevent them from triggering. In November 2013, the Christchurch-based journalist Rebecca Macfie published the book Tragedy at Pike River Mine: How and Why 29 Men Died, based on research and interviews into the causes of the disaster. Several commentators criticised successive National and Labour Party governments for deregulating safety in the mining sector and some also argued that the Engineering, Printing and Manufacturing Union (EPMU), which had several members at Pike River, did not do enough to prevent the tragedy. In the days after the explosion, EPMU leader Andrew Little (who later became Labour Party leader) said there had been no problems at Pike River Coal and defended its safety record. The disaster has led to calls for New Zealand to introduce a crime of corporate manslaughter, and in 2013 Labour leader Andrew Little introduced a private members' into the ballot that would introduce a new crime modelled on the United Kingdom's Corporate Manslaughter and Corporate Homicide Act.
