The names of three more identified victims of the White Island eruption have been formally released by police.
Australian brothers Matthew and Berend Hollander, aged 13 and 16 respectively, have been formally identified, as well as 32-year-old Australian Karla Mathews.
Matthew and Berend's parents, Martin and Barbara, have yet to be identified and were among the missing earlier this week.
Karla Mathews was travelling with her friends Richard Elzer, 32, and Jason Griffiths, 33, on the cruise ship Ovation of the Seas when they visited White Island on Monday. Elzer has yet to be formally identified by police but was among those who remained on the island following the eruption.
Griffiths succumbed to his injuries and died in hospital.
The official death toll is currently sitting at 16 after another victim, repatriated to Australia, died in hospital on Saturday.
Earlier on Sunday, police named four more victims of Monday's eruption: 24-year-old New Zealander Tipene James Te Rangi Ataahua Maangi, 15-year-old Australian Zoe Ella Hosking, 53-year-old Australian Gavin Brian Dallow and 51-year-old Australian Anthony James Langford.
Dallow was Zoe's stepfather. His wife and Zoe's mother, Lisa Dallow, is severely burned and has been repatriated to Australia.
Police named another victim on Saturday evening - 21-year-old Krystal Browitt, from Melbourne. She was reportedly travelling with her family in celebration of her 21st birthday.
Police are continuing to search for two remaining bodies on and around the island following the successful recovery of six bodies on Friday.
Deputy Police Commissioner Mike Clement says they are not giving up.
"There will come a time when we've done everything that's sensible to do. We're not there yet, and we don't give up easily. There's a whole lot of disappointed people behind me."
Responders are describing each mission as difficult, both mentally and physically, with dehydration proving to be a problem.
Staff from police, the Defence Force and Navy remain in Whakatane.
"We are now debriefing, reassessing and coming up with a new plan going forward," said Deputy Commissioner John Tims.
"Our staff and partner agencies continue to work tirelessly as we approach one week since this tragic event and I wish to thank them for their dedication."
