A 15-year-old Adelaide schoolgirl and her family are among those missing in the White Island disaster.

Gavin Dallow, 53, his partner Lisa Hosking, 48 and daughter Zoe Hosking were on a two-week Royal Caribbean cruise around New Zealand which left last Wednesday, the Adelaide Advertiser reported.

Zoe's school, St Aloysius College, released a statement saying information was scant but that the Year 9 student was definitely among the missing.

"Our thoughts and prayers are with Zoe and her family," the school says.

"We know that you share our sadness at this time. We turn to our loving God to give us strength and courage in the days ahead."

Dallow's family confirmed to the Advertiser that the trio had been on a day trip to White Island on Monday and were yet to hear if they were safe.

Gavin's father Brian Dallow said he had been in touch with authorities but hadn't heard from them since last night.

""I'm wrecked … we had the phone with us all last night," Dallow said.

"We don't know anything, we haven't heard anything."

The Dallows said a family member would fly to Auckland to search hospitals for the trio.
