The article focusses pretty heavily on local production of "sustainable aviation fuel", but the draft Tourism Environment Action Plan looks at lots of ways to make NZ tourism more sustainable. They are currently seeking public input. From MBIE:

The draft action plan aims to ensure tourism has a positive impact on the natural environment and proposes 6 focus areas to achieve this. These areas or Tirohanga Hou (new pathways) are:

• Tourism journeys are decarbonised
• Tourism champions biodiversity
• Visitor management is optimised for te taiao (nature)
• Accelerated technology uptake and innovation enable regeneration
• Tourism businesses are incentivised and enabled for sustainability and regeneration
• The tourism system and its levers are optimised and resourced to support regeneration

Each area has multiple actions that will deliver positives not only for the environment but for communities and tourism operations.

Some actions see the tourism industry working with communities to create a picture of what healthy visitation looks like. Others focus on supporting and incentivising tourism operators to adopt sustainable or regenerative practices. Rapid investment in low-carbon technologies for long-haul travel is another key action.

The full draft plan is here, along with details about how to make submissions - including an online survey.

Edit: Just did the survey. It takes about 10 mins.
