The progressive, irreversible lung disease is caused by long-term exposure to silica dust, which is created when artificial or engineered stone is cut.
E Tū union's construction industry co-ordinator Ron Angel believes the silica dust threat is not as well known in New Zealand as other building site health risks like asbestos.
"The professional concrete cutters, they use the wet cutting, they use the masks.
"I think the issue is the smaller tradespeople that don't really have the facilities and just aren't really aware of it."
Angel said he has seen tradies forgoing the proper safety gear, especially during the Christchurch rebuild.
"People say 'I'm just making a small cut, it's just a quick job, so really it's not a problem'.
"But each on of those little cuts, they all add up over time to create a debilitating and incurable disease."
He said WorkSafe have a big job on their hands to educate the sector on the risks, and actually enforce their safety protocols.
"We still have problems with asbestos and that's come a long way.
"Silicosis needs that same level of action from WorkSafe."
