Many expressed also gratitude for the rescuers and Pike River chief executive Peter Whittall.
"RIP Miners and Heartfelt Sympathy to their families and all those involved with this tragedy. Peter Whittall you were amazing -- thank you for your calmness and honesty and thanks and blessings to all that were involved. God bless xx," Pam Hanretty wrote.
Chris Barr from Hamilton posted "A dark day for NZ. One explosion and 29 families ripped. My thoughts with all of you struggling through this tragedy. To the rescuers - Never for a second doubt yourselves. You did everything you could. This was out of your hands and your rescue attempts were 110 per cent."
