As the popularity increased, more resources were put into track maintenance and facilities. Today, the track is well defined and serviced and capable of being walked by a wide age group. A number of commercial operators now provide guiding facilities and packing ability, thus allowing a wider age group to enjoy this extended walk. From the south, the Karamea-Kohaihai road is unsealed for the last 4 kilometres, as at January 2018. From the north, the Collingwood-Browns Hut road is sealed as far as Bainham, then unsealed for the final 12 kilometres, as at January 2018. This access road became an all-weather road in 2014, when the last of three major fords near Browns Hut were bridged. Before the area became a National Park mountain biking was permitted on the track. As a National Park use of the area comes under the National Parks Act 1980, which stipulates that vehicles are not allowed to be taken off formed roads. This prevented mountain bikers from using the track and debate has been on-going to allow at least some access. The New Zealand Conservation Authority decided to permit mountain bike access again from May 2011 for the winter months when tramping numbers are low. As of 2016 the Mountain Bike Trial period ended, and mountain biking became a permanent option, though still only between 1 May and 31 November each year. Mountain biking is now allowed each year from 1 May to 31 November for groups not exceeding six riders.
