Gibson v Maritime New Zealand: what every Queensland mining officer needs to read before 1 June 2026

By Scott Graham · April 2026

The NZ High Court has just upheld the conviction of the former CEO of Ports of Auckland for a due diligence failure under New Zealand's health and safety legislation. The decision should be sitting on every Queensland mining officer's desk right now, because the duties that convicted Tony Gibson are about to become live in Queensland on 1 June 2026.

This isn't a story about a bad operator. That's what makes it worth reading.

Who Gibson was

By every account that came out in the proceedings, Gibson was exactly the kind of CEO most boards say they want on a high-risk operation:

• He was engaged and visible
• He ran workshops with frontline staff
• He pushed hard engineering controls over behavioural ones
• He personally drove the introduction of safer equipment after seeing unsafe work first-hand
• His workers, including ones who gave evidence, called him a good boss

He was convicted anyway.

What actually failed

The exclusion zone around operating cranes was a critical control. It existed as a policy. Training covered it. The documentation was

in order. But no one was reliably checking whether it was being applied on night shift. It wasn't. A container fell, and a thirty-one-year-old man died.

The court's finding wasn't that Gibson was careless or disengaged. It was that the verification loop on the one critical control that

mattered on the night a man died was not closed. The information about how the control was actually performing on shift never made it to the level where someone could act on it.

That's the gap. Not absence of policy. Not absence of training. Absence of verification.

Why this matters for Queensland

From 1 June 2026, officers of Queensland mining corporations have a positive duty under s47A of the Coal Mining Safety and

Health Act 1999 and s44A of the Mining and Quarrying Safety and Health Act 1999 to:

• Gain an understanding of the hazards, risks, and critical controls associated with the corporation's operations
• Ensure the corporation has appropriate processes for receiving and considering information regarding incidents, hazards, risks, and critical controls, and for responding in a timely way

Read those duties carefully. They aren't passive. They're not asking you to be informed in a general sense. They're asking you

to know the critical controls specifically, to know how information about those controls reaches you, and to ensure the corporation actually responds when it does.

That's a feedback loop duty. And it's exactly the duty Gibson was found to have failed.

Four questions worth putting to yourself before 1 June

If you're an officer of a Queensland mining corporation, these are the questions I'd be testing against your current arrangements right now.

1. Can you name the critical controls for each principal hazard at your operation?

Not the hazards. Not the risks. The specific controls. If you can't name them, you can't fulfil the duty in s47A or s44A.

2. How does information about whether those controls are being applied actually reach you?

Through what report. At what frequency. With what verification behind the numbers. "It's in the monthly safety pack" isn't an

answer, that's a process for receiving information about indicators, not about controls.

3. When a control fails or is bypassed at three in the morning on a Sunday, what's the path from that event to your desk?

And how long does it take to get there? If the answer is "it depends" or "the next monthly meeting", the loop isn't closed. This is precisely where Gibson's case turned.

4. When it does land on your desk, what does "responding in a timely way" look like in practice?

Could you demonstrate, after an incident, that you responded? In what document, with what evidence? "Timely" doesn't mean fast, it means proportionate, recorded, and visible.

The Queensland stakes are higher again

Gibson was convicted under New Zealand legislation. In Queensland, s47A and s44A sit underneath industrial manslaughter

provisions. An officer who fails the due diligence duty in a way that contributes to a worker's death isn't just facing a personal prosecution under the safety legislation, they're facing the possibility of an industrial manslaughter charge.

The combination is unforgiving. Gibson did a great deal of good and was still convicted. None of his engagement, visibility, or investment protected him because the verification loop for one critical control was not closed.

Queensland operators have until 1 June 2026 to make sure theirs are.

CCM diagnostic for Queensland mining officers

I've partnered with Wayne Reilly to offer Queensland mining company officers a Critical Control Management Diagnostic — a structured review designed specifically around the s47A and s44A officer duties, with verification loops as the central focus.
