Soon after this photo, two boys were dead
TRACEY Woolley's voice is barely above a whisper as she answers the question. Her voice cracks but her message is resolute.
At her side, 18-year-old Denver Woolley listens as his mum talks about meeting the three dads in a rescue helicopter who saved her son's life, but were unable to save his twin.
Denver has his own story to tell, of an hours-long fight for survival in raging water, logs the size of trucks hurtling past, and a ponga tree that skinned his arms and saved his life, but for now he's quiet.
This isn't a story about one teenage boy. It's about five, and what happened when an everyday summer outing turned to tragedy on February 3.
Three - Denver and friends Nathan Phillips and Jason Lee - would survive when a sudden downpour turned the normally placid creek below Waitakere Ranges' swimming hole Cascade Falls, about 30km west of Auckland, into a terrifying torrent of debris-choked water.
Two boys would not.
One was Sosiveta "Sosi" Turagaiviu, described by his friends as kind and generous, by his school as a keen basketballer, and by his pastor as a hard worker who toiled at KFC so he could buy a car he wouldn't live to drive.
The other was Mitch Woolley - son to Tracey and her husband Mike, and Denver's twin brother.
When Denver last week met the Auckland Westpac Rescue Helicopter crew who saved his life, it was to say thank you and to put names to faces he didn't - in the trauma of the rescue - remember very much.
His mum also wanted to put a face to "those anonymous people that go about their duty" for an organisation she has long supported, and is now sharing her family's story for the Auckland Rescue Helicopter Trust's new chopper annual appeal.
"You never actually believe, or even hope, that it will be you that needs them. It's hit personally this time, so it's nice to know that it's real people and they actually wanted to meet us as well.
She wants to let them know that rescuing Denver "meant something to them".
What did it mean to her?
"Everything," she says softly.
"I couldn't imagine life if he had gone as well."
'WE'D HAD A REALLY FUN DAY'
It was a typical teenage boy kind of day, that first Saturday in February.
Friends. Fun. Food. More fun.
Mitch was the driving force behind the boys' day together. Denver and their friends were back at Massey High School, but he was a working man now.
The previous November he'd started a trial as a marine systems engineer; the week before the tragedy he accepted a permanent offer of employment, Ms Woolley says.
"They'd actually decided within the first week he'd started that they wanted him in the job. The trial was making sure it's what he wanted."
When Mitch said he'd shout Denver and three friends paintballing, his mum wasn't surprised - even though it cost hundreds.
"All his first pays were about other people. He'd bought me a pair of greenstone earrings and the day before [he died] he'd bought Denver an exercise thing that he'd always liked.
"He was on a trainee wage, so he wasn't earning very much, but it was all about doing things for his mates and spoiling his family."
Ms Woolley was with the boys that last Saturday morning.
"We'd had a really fun day."
Returning to the family home, she fixed the teens' lunch. They then decided they wanted to go swimming at the nearby Cascade Falls.
It was 4pm when Ms Woolley dropped the boys at Falls Rd car park, 15 minutes walk from the waterfall.
She'd be back in an hour, she told them as they set off.
"I went down [and] got Lotto, drove up home and the rain started. It was really heavy, so I drove straight back down and it was ... disaster. Even driving down from the water running off the land was just so sudden and so heavy."
The worried mum was back at the car park by about 4.20pm, but she could do nothing.
'THE WATER ... JUST WASHED US IN'
Denver was swimming when it started raining. He wasn't alarmed.
"We were in the water already and we didn't mind. It was just a little bit more water."
But it got cold, and Denver noticed more water coming out of the waterfall. They decided to leave, but there was a problem.
While Mitch and Sosi were on the track-side of the swimming hole, Denver, Nathan and Jason were on the opposite side.
The cliff behind their ledge was too steep to climb. And the water in front of them was rising "so quick", Denver says.
"In three minutes it went from the bottom of my feet to the top of my ankles."
Nathan was the first to fall in.
Mitch and Sosi ran after him. Denver wouldn't see either alive again.
On the rapidly disappearing ledge barely a minute passed before he and Jason were "pinned against the wall".
"We had nowhere to go. The only way to go was to fall in. Jason said he was scared and I was trying to be brave and all, but I knew it could go one of two ways - we get washed in and we end up OK or we get washed in and that's it.
"I thought we were gonna die right then."
Within 10 minutes the inevitable occurred.
"The water just didn't stop rising, it just washed us in."
Immediately separated, Denver next saw Jason - who made his own way to safety - at Waitakere Hospital.
Nathan, who fell first, would escape the floodwaters, raising the alarm when he flagged down two tourists who called emergency services.
THE PONGA TREE
That fight started with a fortuitous decision.
After the floodwaters washed him from the waterfall ledge, he went far and fast - he estimates at least 600m in 40 seconds.
"It was like ... whitewater rafting. Times three. [There were] logs coming down the size of trucks and wiping out every tree around me.
"There's no words that could describe the amount of power that that water had."
Despite the force of the water, Denver managed to swim to a ponga tree and wrap his arms around it.
The tree stayed standing. He stayed holding on to it for over two hours in the freezing water as it ripped his arms to shreds.
Eventually he was rescued by the helicopter.
It's a different life for the Woolley family now, but there are moments of grace.
The two mothers who lost sons share a bond others cannot, and talk often, Ms Woolley says.
"[Sosi's mum] calls me her sister."
There are moments of gratitude, too, for the support and love from those they know and those they don't, from emergency responders to family to strangers in the car park.
They could "never even begin to thank or acknowledge" all, she says.
"This is an opportunity to say that we've appreciated it."
And then there's the rescue helicopter crew, fathers all, who saved more lives than one that day.
"Because what we're going through is pretty rough," Ms Woolley says.
"But it could've been a whole lot worse."
