A tense and nervous wait for those involved in the rescue of Thailand's trapped football team.

Eight boys have been rescued, but four boys and their coach are spending another night trapped deep underground.

Cave expert Andy Eavis is friends with many of the divers involved in the rescue.

He told Larry Williams everyone with a stake in the rescue operation is hoping and praying the boys will be OK.

"They are doing very well, it's working to plan and it's fingers crossed for the other five. I have a bottle of champagne all ready for when the last one comes out okay."

The rescue is set to resume this afternoon New Zealand time.
