The national Institute of Directors backs the expectations placed on directors, regardless of the company size or number of employees, saying ultimately the ''buck stops'' with company directors.
Law firm Duncan Cotterill's health and safety specialist lawyer, Stephanie Grieve, said the director liability issues were highlighted by the recent conviction of Ms Davis, the sole director of the company which owned the ill-fated Easy Rider fishing boat, which was overloaded, swamped and sank in Foveaux Strait last year, killing eight people.
''Under the new [health and safety] regime, we expect more cases of directors who are not operationally involved being found liable for health and safety breaches, in circumstances where they have not obtained key knowledge on health and safety performance in order to ensure it is adequate,'' Ms Grieves said in a statement.
Ms Grieve said section 56 of the Health and Safety in Employment Act 1992 will be superseded in the new health and safety regime, which will impose direct obligations of due diligence on company directors and officers.
''Nothing has changed in terms of liability. After people advise administration on health and safety issues they must act; ultimately the buck stops there with directors,'' he said when contacted in Kuala Lumpur yesterday.
Mr McLauchlan is chairman of Scott Technology, Pharmac, UDC Finance and Dunedin International Airport Ltd, and also a director on the boards of 14 other, separate companies.
When asked if the expectations of health and safety knowledge and responsibility was the same for a company with 20 employees, or 750 employees, he said ''absolutely''.
''There has to be a company culture of reporting [all incidents] to the board; all accidents and near misses ... have got to be reported to the board,'' he said.
Ms Grieve said the Easy Rider case illustrated what has been a problem, with section 56(1) of the Health and Safety in Employment Act 1992, from the outset, in that it has generally only applied where a director was close to core operations, as opposed to the Pike River Coal mine case, in which no directors were charged.
After the 2010 deaths of 29 miners in the Pike River Coal mine, there was widespread criticism by victims' families of the lack of accountability by management, no less so than when charges against mine boss Peter Whittall, under the Health and Safety in Employment Act, were dropped last December.
Asked if the Pike River deaths had played a role in the health and safety changes, Mr McLauchlan said: ''Yes, Pike River was a catalyst.''
Ms Grieve said even though Ms Davis, who is yet to be sentenced, had no involvement in the direct decisions made the day Easy Rider sank, she was charged with failing to take all practical steps to ensure the safety of contractors; the vessel deckhands.
''That was because she had, or ought to have had, knowledge about health and safety issues relating to the vessel,'' Ms Grieve said.
Mr McLauchlan said the directors' institute and the Ministry for Business, Innovation and Employment last year ran roadshows together around the country, specifically outlining directors' health and safety responsibilities, and have a template on the institute's website, on health and safety requirements and obligations.
