Major tourism organisations, including Air New Zealand and the Tourism Industry Association, are currently working on proposals for a large central fund for tourism infrastructure.
Prime Minister John Key has said funding ideas, including a tourist tax or levy, would be considered.
United Future's new conservation levy policy has been released as part of its new environmental policy package.
Other policies in the package include:
• A $5 million annual grant to promote electric vehicle ownership, that would allow up to $5000 to be claimed, or up to 30 per cent of the cost of a vehicle, whichever is smaller. The scheme would also apply to businesses replacing company fleets.
• A $10 million per annum contestable fund for promoting innovation and research into the environment.
• A fund of the same value for homeowners to purchase solar panels and similar units, with homeowners able to claim up to $5000 or 80 per cent of the cost, whichever is smaller.
• Develop new protection categories for marine reserves that would ban commercial fishing and allow recreational fishing.
• Get government to take a lead in encouraging owners of unproductive farming land to gift it to public ownership so it can be planted with native trees and act as a permanent "carbon sink".
