Labour has proposed a new corporate homicide offence for workplace deaths, drawing support from families of the 29 men killed at Pike River Mine. The proposal raises a central question for New Zealand: how would the new offence differ from existing workplace safety law, and what would be required to prove it?

Labour has promised to introduce a corporate homicide offence if elected, with a maximum sentence of life imprisonment for an individual and a fine of up to $10 million for a company. The proposal has been welcomed by families of workers killed in the 2010 Pike River Mine disaster, who have campaigned for stronger accountability following workplace deaths.
According to RNZ’s report, Labour workplace relations and safety spokesperson Jan Tinetti said the proposed offence would apply where a person or company owed a legal duty of care, exposed someone to a risk of death or serious injury, and a death resulted. Tinetti said the threat of criminal penalties was intended to encourage employers to strengthen safety practices before a fatality occurred.
The proposal remains a party policy, not an enacted law. Its precise legal tests, including the degree of fault and causal connection prosecutors would need to establish, would need to be assessed against the text of any bill introduced to Parliament.
Pike River Families Seek a Lasting Legacy
The Pike River Mine disaster killed 29 workers on the West Coast in November 2010. Among them were Ben Rockhouse, aged 21, and Milt Osborne. Their family members, Sonya Rockhouse and Anna Osborne, have campaigned for stronger workplace safety laws, including a corporate manslaughter offence.
Rockhouse welcomed Labour’s announcement and expressed hope that stronger penalties would encourage those responsible for workplaces to make safety a priority. She also acknowledged that no subsequent law could undo the losses suffered by the families.
The families’ campaign extends beyond this proposal. Rockhouse and Osborne have also opposed changes to workplace safety legislation that they believe could increase the risk of another disaster. The minister responsible for those changes, Brooke van Velden, has argued that they would provide greater certainty, reduce compliance costs and improve safety. Labour has said it would repeal the changes.
These are distinct policy questions. A new offence would address criminal liability following a workplace death, while the wider health and safety framework determines what employers and other duty-holders must do to identify and manage risks before anyone is harmed.
What New Zealand Law Already Provides
New Zealand already has criminal penalties for serious breaches of workplace health and safety duties. Under section 47 of the Health and Safety at Work Act 2015, reckless conduct that exposes someone to a risk of death or serious injury or illness can attract a maximum prison term of five years for an individual. The maximum fine under that section is $3 million for a company or other body covered by its corporate penalty provision.
A prosecution under section 47 does not require a worker to have died. It concerns reckless exposure to serious risk. Labour’s proposed corporate homicide offence, as described by RNZ, would instead require a death and carry substantially higher maximum penalties.
That distinction matters. The existence of a new offence would not, by itself, establish whether a particular death was criminally caused by a company or individual. Prosecutors would still need evidence identifying the relevant duty-holder, the conduct alleged to have breached the law, the required level of fault and the connection between that conduct and the death.
Would a New Offence Prevent Workplace Deaths?
Will this in fact make New Zealand stronger? For workers and their families, the practical test is whether the proposed offence would contribute to safer workplaces and clearer accountability when a preventable death occurs. Higher maximum penalties could change the consequences of a successful prosecution, but their preventive effect would also depend on the clarity of employers’ duties, the likelihood that serious breaches are detected, the quality of investigations and the capacity to bring cases to court.
Tinetti told RNZ that she hoped the proposed penalties would encourage stronger safety practices so that prosecutions would not be necessary. She cited the United Kingdom’s experience with corporate homicide legislation, saying it had recorded 30 convictions since the offence was introduced in 2008. That figure describes prosecutions under a particular legal framework; on its own, it does not establish how many workplace deaths the law prevented.
The details of Labour’s proposed offence will therefore be important. Parliament would need to determine how it relates to existing health and safety offences, what must be proved against a company or an individual, and how responsibility is assigned when decisions are spread across directors, executives, contractors and site managers.
Accountability Begins Before a Fatality
For the Pike River families, the proposed offence is part of a long campaign to ensure that workplace deaths are met with meaningful scrutiny and accountability. For workers in mining, construction, manufacturing, agriculture and other hazardous industries, the immediate concern is whether risks are recognised and controlled before a tragedy occurs.
A corporate homicide law would address one part of that system: the consequences when a death has occurred and the legal elements of an offence can be proved. Effective prevention also requires clear safety obligations, workers who can raise concerns, credible inspections, properly resourced investigations and action when dangerous conditions are identified.
The measure of the proposal will be found in its eventual legislative wording and, if enacted, how it operates alongside New Zealand’s existing workplace safety protections.
