Another political party has called for a tourist tax to help fund conservation.
United Future want a $25 fee placed on tourist visas with all revenue going towards maintaining and upgrading the conservation estate.
Leader Peter Dunne said the cost of maintaining walking tracks, rivers and lakes currently fell on locals.
"This policy allows the costs of maintenance and upgrades to be shared amongst all the people who make use of our conservation areas."
The new policy comes after the Green Party last month announced a "Taonga Levy" to fund conservation efforts and regional tourism, and that would increase current border charges for international visitors by between $14 to $18 to a total border levy of around $40.
