We are an intergenerational company whose success relies on thriving New Zealand ecosystems, flourishing communities, and on good business decisions that achieve the aspirations of our shareholders. 

Our Commitment

As a company we are an integral part of daily life in New Zealand and we’re acutely aware that our every action, good and bad, has a marked impact on the wellbeing of our communities — today and in the future. 

At Contact, sustainability means making every decision, every action, count for the long run. It means using Our Tikanga to make the best decisions for today and tomorrow. Decisions our kids would be proud of. It’s about making sure we look after their future, New Zealand’s future. 


Renewable, reliable energy, responsibly delivered

We're committed to a sustainable energy future for New Zealand. To us, this means balancing our commitment to renewable energy, while maintaining reliable access to energy for our customers.

In recent years we’ve invested in building our renewable, flexible and reliable generation portfolio which has helped us to reduce our greenhouse gas emissions from generation by 57% since 2012. We have developed new geothermal power stations, which, alongside our existing geothermal and hydro power stations mean that our generation is now more than 80% renewable. We maintain thermal generation options for when the market needs extra energy, and we’ve also got New Zealand’s only gas storage facility which adds flexibility to our portfolio. We also hold resource consents for other geothermal projects should the need for further electricity in the market be required.

Positively part of our communities

The nature of our business means our operations can sometimes impact on the environment and the people who live within it, so we work hard to be a good neighbour and a positive part of the communities we live and work in.

Looking after our ecosystems

We’ve made a commitment to take care of the natural resources that we rely on so that future generations of New Zealanders can continue to enjoy them too. It’s all about balance and we’re working to maintain that balance every day.

New Zealand is rich in natural resources and intricate ecosystems which sustain thriving and diverse species, environments and communities. 

Our operations can have wide-ranging impacts on water, rivers, birds, animals and plant life. The range of different impacts in different regions means that we have site specific management plans for local biodiversity. Across our sites in 2021 we caught 3,354 pests, planted 29,068 trees, transferred 330 tuna (freshwater eels) downstream in the Clutha catchment (including 19 migrant tuna), and transferred 51.8kg of elvers upstream of the Roxburgh Dam. Contact has also planted more than 125,000 native trees over the last three years. Since our restoration and protection programmes began, we have protected over 130 hectares of land. This includes planting, fencing and an increased focus on pest management. We continue to support local community groups such as Kids Greening Taupō to help build awareness and love for our environment in the next generation.

Our biodiversity commitment

Climate change is a significant global issue with the potential to adversely affect the environment, people and the economy. Through our investment of around $1.7bn in building our flexible, reliable and renewable generation portfolio, Contact’s generation is now more than 80% renewable. This has resulted in a 57% reduction in our greenhouse gas emissions from generation since 2012.


We know that water is a precious taonga that we all share and need to maintain for current and future generations. The growing range of competing demands on water means that everyone needs to do their bit to look after this shared resource. That includes us. 

In 2010 we built the award winning Wairākei bioreactor to help us reduce our impact on the Waikato River. The bioreactor turns hydrogen sulphide, which is harmful to freshwater ecosystems in high concentrations, into harmless dissolved sulphate particles using natural enzymes. This was an innovation developed by our team right here in New Zealand.

Financial Sustainability

We have more than 63,000 shareholders and 1,000 bondholders around the world including many Kiwi families, investment firms, professional investors and superannuation funds.  Each of them rely on us to deliver sustainable financial returns now and into the future.


Increasingly investors are focusing on climate change and its potential impact on the environment, people and business.  In recognition of this and our commitment to sustainability, Contact has undertaken market leading sustainable finance initiatives.  In 2017 Contact was the first company in New Zealand to establish a Green Borrowing Programme, in 2019 we set up a sustainability linked loan and in 2020 we became the first company in the Asia-Pacific region to list our bonds on Nasdaq’s Sustainable Bond Network.


Contact has invested around $1.7bn in building a flexible, reliable and renewable generation portfolio to address climate change. Contact's generation is now more than 80% renewable, with a 57% reduction in our greenhouse gas emissions from generation since 2012.

Resource Management

Our business impacts on natural resources so we extensively monitor the effects our operations have on the environment, and work towards reducing these at all times. 

Sustainability Reporting

We report on our progress against sustainability objectives in our Annual Reports.
