American tourists who were buried "in volcanic ashes and toxic gases" in the Whakaari / White Island tragedy have shared the last picture taken of them shortly before the volcanic eruption.
Rick and Ivy Kohn Reed suffered critical injuries in the December 9 tragedy when the popular North Island tourism destination erupted underneath them, leading to the deaths of 21 people.
The American couple were recently airlifted home to the US to continue with their recovery from the severe burns they suffered.
• White Island heartbreak: Badly burned mother can't attend daughter's funeral
• White Island eruption: Emergency management plan not finalised when erupted
• White Island: American tourists burned in the eruption hopeful they will be home soon
• New White Island eruption response meeting minutes, reports and plans released
In an update to a GoFundMe account set up to contribute to support the couple, Ivy has posted a photo of the pair on White Island prior to the eruption.
In it, the Americans are pictured smiling, with Rick's arm around his wife, while steam rises from the White Island crater behind them.
"This is the last picture taken of us before our lives changed forever," Ivy wrote.
"Approximately 15 minutes after this was taken, the White Island volcano erupted, burying us in hot volcanic ash and toxic gases. We survived, were rescued and spent almost 8 weeks in a New Zealand Hospital receiving critical care treatment.
"Our dream vacation turned into a nightmare that we are still trying to comprehend."
Ivy's brother, Barry Kohn, revealed in late January that the pair were getting ready to return to America.
Both had endured numerous surgeries.
Their return home had been delayed while Rick underwent skin regrafts on his ankles and physical therapy to help him start walking again. He suffered burns to 30 per cent of his body in the eruption.
Ivy suffered burns to her right leg, hands and face.
Barry Kohn – who travelled to New Zealand to be at the bedside of his loved ones - also shared a photo of his brother at Auckland's Middlemore Hospital, with Barry giving the camera the thumbs up signal.
He also wrote on an earlier update on the online fundraiser: "I have been lucky enough to spend the last few days in Auckland with Ivy and Rick.
"It has been both heartbreaking and encouraging at the same time. I was taken aback when I first saw them with my own eyes, as no one is accustomed to seeing their loved ones laid up and recovering from volcanic burns.
"However, their overall positive attitudes and healthy spirits have really shown through."
Writing in her own update – the first public comment she has made since the tragedy - Ivy thanks everyone who had offered "support, prayers, good wishes, cards, texts, messages and calls", saying they had "helped us through some tough days".
But she added: "The next year will be the hardest of our lives while we try to rehab and regain as much functionality as possible.
"We have returned home! This is happy news we wanted to share, but it is also scary, as we figure out what we can and can't do."
Ivy signed off her message by writing: "Much love".
Meanwhile, fellow survivor, 25-year-old Kiwi tour guide Kelsey Waghorn also provided an update online about her ongoing recovery, saying she was "doing really well".
Two days after Whakaari spewed steam and toxic gas from its depths, she had her arms, hands and a small portion of her stomach grafted.
"My legs, lower back and some touch ups on my upper arms had their donor/cadaver skin removed and were grafted on December 27th," Waghorn wrote in an update on a Givealittle page set up to support her and her family.
As this involved harvesting skin from her back and butt a second time, as well as some strips from her upper thighs, Waghorn wrote the procedures were uncomfortable, "to put it gently".
"By this stage, I'd been [painfully] upright only twice between these two graftings with a lot of assistance from my beautiful physio, family and a handful of nurses."
The marine scientist has undergone more than a dozen surgeries since the volcano blew.
"So there was a lot of blood, sweat and tears put into getting me where I am today after my final graftings."
Waghorn remains in hospital two months on from the volcanic blast.
"Monday marks 9 weeks since Whakaari decided she would clear her throat. 9 weeks since I received full thickness burns to about 45% of my body. 9 weeks since I lost work colleagues and good friends."
Fellow guides Tipene Maangi and Hayden Marshall-Inman were killed by the eruption.
Nineteen-year-old tour guide Jake Milbank remains in Middlemore Hospital, suffering burns to 80 per cent of his body.
"I am fairly mobile now, albeit wobbly and minus some strength," Waghorn wrote.
"I am slowly regaining the use of both of my hands - my right is worse than my left. But I'm working on that every day."
