A worker has been injured after becoming trapped inside a wastewater tunnel in Auckland.
The accident happened at Watercare's Central Interceptor project in Sandringham on Saturday morning.
The worker was pulled out on a stretcher by crane, Newshub images showed.
"Hato Hone St John was notified of a workplace incident in Sandringham at 8:55am and responded one ambulance, two rapid response units and one manager to the scene," a St John spokeswoman said.
"Our crews assessed and treated one patient who was transported to Auckland City Hospital."
In an update, a Watercare spokesperson told Newshub construction worker received "minor injuries only".
"The man was trapped between a sheet pile (similar to a retaining wall) and a beam whilst working inside a six-metre-deep concrete chamber," they said.
"The worker was not involved in tunnelling operations. The site will remain closed for the rest of the day."
Watercare chief programme delivery officer Shayne Cunis said: "We are relieved our worker is not seriously injured and we'd like to thank emergency services for their quick response. Safety remains our first priority and we will be investigating this incident."
WorkSafe has been notified.
The billion-dollar Central Interceptor tunnel, started in 2019, runs for 13km between Western Springs and Māngere to reduce overflows in wet weather.
It's construction was a joint venture between council-controlled Watercare and private firm Ghella Abergeldie JV.
The project was due to be completed by mid-2026.
