A routine incident at New Zealand’s deepest gold mine has given WorkSafe inspectors rare, real-world proof that years of joint safety training are paying off.
WorkSafe has been embedded with the Snowy River gold mine project, near Reefton, since 2018. But in November 2025 safety lessons were put to the test.
A dump truck operator at the mine spotted what he thought was smoke rising from his vehicle during a during routine work, he acted immediately. He triggered the automatic fire suppression system and activated emergency protocols immediately. Within minutes, all underground workers had retreated to self-contained refuge chambers – airtight shelters capable of protecting workers from smoke and gas for up to 48 hours.
The “smoke” turned out to be harmless steam from the engine’s coolant system. But the response was anything but routine.
“Speed is everything in an underground fire,” says WorkSafe extractives chief inspector Paul Hunt.
“These chambers are lifesavers – and historically, underground fires are among the most dangerous events in mining.”
WorkSafe’s lead mines inspector John Ewen, who has worked alongside the site’s team, says the response reflected something that can’t be fabricated.
“Trust, respect, consistency and communication is key – even if it means fielding calls at two o’clock in the morning. It comes down to years of rigorous inspections and reviews, so mine operators know they can call me any time if they’re not sure about something.”
On a recent site visit, John Ewen quizzed a new employee about emergency procedures. The worker answered without hesitation. “It shows the company is taking safety seriously. It’s so rewarding to witness.”
He says had the incident been a real fire, he is confident every worker would have made it out safely.
But Paul Hunt is clear: one strong result doesn’t mean the job is done.
“This shows the systems in place are quite good. But there are no guarantees – there could be a serious incident next week. You can never get too confident, otherwise you’re in trouble.”
Snowy River general manager Patrick Enright credited the whole team. “Through training and a programme of emergency exercises with internal and external input, the team have come a long way. It is very comforting to know that if a situation does arise, the team are well placed to handle it.”
Gold production at Snowy River is expected to begin later this year.
