Wife pays tribute to 'wonderful' Auckland man who died attempting to climb Mount Kilimanjaro

The wife of Brett Clark, an Auckland man who died while attempting to climb Mount Kilimanjaro in Africa last week, has paid tribute to her late husband.

It was a 20-year-dream for Mr Clark, who was climbing Mount Kilimanjaro in Tanzania with his eldest son last week.

Wife Lisa Clark paid tribute to the "wonderful man" in a heartfelt Facebook post. "He was a wonderful man with an amazing amount of energy," she wrote.

It is believed he got altitude sickness and was taken to hospital. He died on Friday (local time).

"We are devastated. We can't believe it yet," Lisa posted just 45 minutes after the news. Earlier on Friday she posted that he was improving and looked set to be discharged from hospital.

"Before he was unable to, at the last he sent a text. It read: "I love you son, and tell Lisa I love her too." Those are his last words. My heart is breaking. Rest in Peace," Lisa wrote.

A friend also paid tribute to Mr Clark, praising his comical humour, and the University of Auckland's Department of Classics and Ancient History wrote a tribute on Facebook describing Mr Clark as not only a student but a long time friend.

Mr Clark was finishing his masters degree, and had festivals and events planned and booked, Lisa wrote on Facebook.

His 23-year-old son completed the hike to Kiimanjaro's summit (5895m), then returned to later hear of his father's death.
