She had been documenting various parts of their New Zealand holiday, including a visit to the Te Henga Walkway, just 45 minutes away from Auckland.

“17.53km in 5.5hrs,” the Facebook post read.

“Safe to say this was a challenge that was 100% worth the trouble for this incredible part of the world we got to explore. Even with all the mud we slipped on.”

On July 15, Mr McKinnon’s fiance posted an image to Facebook that read, “We must travel in the direction of our fear.”
