Sam Hayes' high altitude drama in Argentina

Samantha Hayes has taken to Instagram to open up about a high altitude drama she faced while mountain climbing in Argentina.

Members of the Newshub Live at 6pm presenter's climbing party had to be flown out after being struck by a medical emergency.

Hayes posted a photo from the summit of Mt Bonete, along with an account of the troubles.

"At 5000m it was a struggle and there were a few tears at the top, in part because two of our group had to be medically evacuated by helicopter from the mountain the day before due to altitude sickness," she said.

The Dancing With The Stars NZ 2018 winner also suggested things could get even scarier, too.

"The weather was perfect for the summit too - not so much today. I'm in my tent, it's snowing and I can hear either thunder or avalanches. I'm going with thunder."

In a recent interview with NZME, Hayes said she took up mountain climbing to get back to her "happy self" after a tough time.

"After an adrenaline-filled few months [on Dancing With The Stars NZ] I was exhausted. The come down after dancing live on TV each week was tough," she said.

"I was physically and emotionally drained and took a couple of months to get back to my usual happy self. I took up mountain climbing which has helped a lot."

Hayes will return to her role on Newshub Live at 6pm alongside Mike McRoberts later this year.
