Then Ms Sutton's friends and her mother will take part in the Kerikeri half marathon on November 15.
They want to commemorate their loved ones' lives by emulating their active lifestyles.
Ms Sutton was a life-long skier and snowboarder who had taken up mountaineering in recent years, while Dr Ogawa was an experienced climber.
"There is a big gap in our lives that was once filled by Nicole and Hiroki, but we do our best to honour them by getting into the wilderness and outdoors ourselves," Mr and Mrs Sutton said, adding that they had recently returned from walking the famous Inca Trail in Peru.
The Suttons have also been touched by the thoughtful tributes paid by the former workplaces of their daughter and her partner.
The University of Auckland, where Dr Ogawa worked as a climate lecturer, planted a Japanese umbrella tree in its grounds in his memory, while environmental consultants Boffa Miskell, where Ms Sutton was a geographic information systems (GIS) analyst, created a "beautiful" book of memories of her time working there.
Mr and Mrs Sutton paid tribute to Dr Ogawa, saying: "He gave up his life for Nicole, trying to protect her, and for that he will always be our hero."
