From July first the price of huts and campsites is going up 18% with the exception of Paparoa; it'll increase a modest 6%.
That means at peak season a hut on the Milford track will be $92 for New Zealand residents.
International visitors pay 50% more.
The fees haven't been reviewed for 4 years and rising construction and maintenance costs and severe weather events are putting a serious squeeze on DOC's budget.
DOC's Director of Heritage and Visitors, Cat Wilson speaks to Lisa Owen.
