Before they set off they shared their planned venture on social media, saying the whole point of the walk was to get people talking.
"We've had a range of people join us, predominantly friends and family, but that has expanded to people who have contacted us via our Instagram page."
The hardest part for the pair was the walk along Ninety Mile Beach. Their bodies strained to get used to their heavy packs as they sank into the sand, while enduring countless blisters.
"We were very happy to get off that beach, definitely underestimated the challenge it quickly became."
Despite the tough start, there have been many highlights - walking through Auckland's CBD to Rotorua's Timber Trail with friends joining them. And they didn't know Mount Pirongia existed until they stumbled across it.
"It was a bit of a climb and really muddy, so rather rewarding getting to the top.
"Paddling the Whanganui river was good as we got off our feet for a bit and meeting people doing that 'great walk' before powering on to turn the eight-day trip into a six.
"It's been a massive experience and we've definitely learned a lot along the way."
