The full Aotea Track loop has now been restored and can once again be enjoyed by trampers.
Ms Barry said the track was a world-class multi-day track, and the centrepiece of the Aotea Conservation Park, which covers more than 40 per cent of Great Barrier and was opened last year.
"It features beautiful native bush including kauri, rimu and the Great Barrier tree daisy, which is unique to the island. Walkers also have the opportunity to see kaka, kakariki and fernbirds among other native wildlife, only a 30 minute flight from Auckland."
Auckland Central MP Nikki Kaye, whose electorate includes Great Barrier, reopened the track on Ms Barry's behalf today.
She said it was a vital tourist attraction and economic asset to the Island.
"Now that the Aotea Track redevelopment is complete, I am going to ask that consideration be given for the track to get greater recognition. I expect to seek advice from local and central Government over the coming months about how we can do this," she said.
"I would love to see more New Zealanders visit and experience Great Barrier Island. The Island is a special part of New Zealand and the Government's investment in the track is an important boost for tourism on the Island."
