A death at a Bay of Plenty sawmill was the result of a medical event, the company says.

Sequal chief executive David Turner told NZME a close friend who contracted to the Kawerau business had a medical event on site yesterday.

“I am grateful for the efforts of team members and the first responders who tried to help him.

“We are now focused on supporting his family through this time.”

A police spokesperson said emergency services were called about 10.50am yesterday.

“Unfortunately, one person died at the scene. The incident has been referred to WorkSafe.”

A WorkSafe spokesperson said they had been notified and were making initial inquiries.
