More details on the deaths of two men in a disused Coromandel mine shaft are expected to be released this afternoon.
The men's bodies were found in an underground mine off a gravel road between Whitianga and Coromandel.
Yesterday, forensic investigators wearing protective clothing emerged from the bush, carrying equipment including an LPG bottle, a funnel, a fan and a large bottle of caustic soda.
Two people living nearby believe the men were making methamphetamine.
Other neighbours were told the men were killed in a P lab explosion but police aren't confirming a drug link.
Whitianga police will be holding a news conference this afternoon.
