Caring For Our Environment

Looking after our unique environment, now and in the future, is hugely important. We’re dedicated to reducing our environmental footprint as much as possible.

We stock water bottles for our passengers that are made of plant-based materials and are collected for specialist composting, and we endeavour to limit our use of plastic bags. We recycle other types of waste, use environmentally friendly cleaning products wherever practical in our boats, and support local efforts to reduce and reuse commercial marina waste. Cougar Line also removes waste for our Marlborough Sounds resident customers free of charge.

Cougar Line staff are all trained in regulations around marine mammals to ensure their safety and wellbeing, which is always a priority when we encounter dolphins, seals or whales in the Marlborough Sounds.

Wherever possible, Cougar Line staff lead by example for the good of our beautiful local environment by following sustainable practises.

Tiaki Promise

Cougar Line supports the Tiaki Promise - a commitment to care for New Zealand, for now and for future generations.

Marlborough Sounds Conservation

By travelling with us, you’re helping us to support local conservation initiatives that are dedicated to enhancing and protecting the natural environment of the Marlborough Sounds for future generations.

As part of our wider conservation work and caring about the beautiful environment that surrounds us, Cougar Line and Marlborough Tour Company support a range of local community initiatives that share a similar vision - to preserve and restore the environment we live and work in, for future generations. Find out more about these great projects:


The Endeavour Inlet Conservation Trust does great work protecting and enhancing the incredible native ecosystems that make the Marlborough Sounds so special and unique.

Driven by the community, the trust supports conservation projects in the hills surrounding Endeavour Inlet, and broader Sounds environmental efforts.

For many years, Cougar Line has supported this work by transporting people and equipment to the inlet at no charge to carry out their important work.

After all, caring for the stunning natural beauty we enjoy every day is everyone’s responsibility.


Cougar Line is proud to support the Marlborough Sounds Restoration Trust by donating our services and funds towards their important work for our local environment.

For many years, the trust has focused on conservation work, primarily the systematic control of wilding pines to encourage the regeneration of native bush and restore the iconic landscape of the Sounds.

If left unchecked, pine trees can overtake native plants as the dominant species. Pine tree by pine tree, this dedicated group of locals has made significant headway into restoring our Marlborough Sounds paradise.

From our daily cruises we can see the great progress being made to restore the splendour of the unique New Zealand native bush.


Kaipupu Wildlife Sanctuary is a mainland island in Picton Harbour, not far from Cougar Line’s base.

This community project aims to restore the 40-hectare peninsula by supporting the regeneration of native bush and wildlife through extensive pest trapping, weed control, planting of native seedlings, the release of native bird species and other conservation work.

The sanctuary, protected by a predator proof fence, is not only a recovering haven for wildlife, but has an environmental education programme popular with school groups from Marlborough and further afield.

Marlborough Tour Company is proud to be a Rimu Sponsor for this fantastic community conservation achievement.


Picton Dawn Chorus is a hugely successful community-driven programme that aims to reduce the number of introduced predator species in and around the Picton township that threaten our native flora and fauna.

New Zealand’s wildlife is under significant threat from these predators that eat native birds, their eggs and chicks as well as lizards and weta. To reduce pest numbers, Picton Dawn Chorus uses humane and environmentally sensitive methods of predator control, and traps are checked regularly by volunteers.

Cougar Line is proud to support this initiative, and particularly the hard work of all the volunteers who give their time in order to bring back the dawn chorus to Picton and its surrounding areas.
