Timaru-born Christine Burke has become the first New Zealand woman to climb the highest mountains of each of the seven continents.
Her mission was completed when she reached the 5642m summit of Mt Elbrus, Europe's highest mountain, in Russia's Caucasus on July 25 Russian time.
"Our summit push conditions were excellent," she says in a post on her website.
"We spent a good time on the summit, maybe 30 to 40 minutes and then made our way down," she said.
She said the descent was much easier than expected and she celebrated at the end with a drink of sprite.
The feat comes almost 22 years after the late Rob Hall became the first New Zealand man to complete the climbs in what was a record time of just under seven months, with his climbing companion the late Gary Ball, Radio New Zealand reported.
Ms Burke is a former Timaru Girls' High School head girl and has worked in Sydney as a partner in a law firm. She was the 11th woman from Australia and fifth New Zealand woman to summit Mount Everest.
