Family and friends of the missing miners gathered last night at the Pike River headquarters in Greymouth, before moving to a nearby Red Cross welfare centre.
Most were reluctant to comment during their anxious wait, but supporters said it was a frustrating time.
"All we can do is wait," said one.
Police were encouraging families to use the welfare centre, which was warm and dry, instead of trying to go to the mine.
The access road is closed except to those involved in the rescue bid.
Ikamatua panelbeater John Batten said everyone in the town - about 46km from the mine - was very concerned.
"Everybody's hoping for the best and it's not looking good at present. It's an absolute major. We're just waiting. It's catastrophic."
