People using Queen Charlotte Track will be asked to pay $5.
"A Queen Charlotte Track Committee initiative was unveiled in Picton this week by project manager Tracy Johnston who explained how the system would operate.
People using the track will be urged to give $5 called the Queen Charlotte Track Tribute to go into a pool of money to be invested in a trust fund to look after the track's best interests.
Ms Johnston said in this "spirit of sustainability" the Queen Charlotte Track committee was setting an example for the rest of the world. The tribute would ensure the 71km track that crosses public and private land will always be a place of rare beauty and freedom.
Users of the walk that is enjoyed by local and international visitors, sports people and nature lovers have paid an environmental protection levy of $2 since 2004 but with more people putting pressure on track resources that amount has been increased.
A ticket machine that will take cash and credit cards will be installed at the Picton Town Wharf where most people leave for the track. Posters in Picton and Marlborough Sounds tourism businesses will urge walkers to contribute $5 each.
The tribute, targeting adult unguided walkers over 18 years is not compulsory or enforceable but the track committee urges tourism operators to support it.
The new system that is believed to be a New Zealand first will be launched later this month when the ticket machine is installed on the Picton Town Wharf."
