We actively make changes in the way we work to reduce our carbon footprint, and preserve our planet for the future.

Taking care of our country

Protecting our Kauri forests

Together with the Kauri 2000 Trust, we launched the Kauri Bond initiative. For every Kauri bond issue we arrange, we aim to plant 100 kauri seedlings.

Saving trees by going digital

Eighty-nine percent of transactions are made in Internet Banking or our Mobile Banking app. With more customers using our digital products, we’re using less paper and saving more trees.

Protecting the environment

We’ve set environmental targets across a range of areas including waste, energy use, and paper, which we’ll track through to 2020.


We’ve been New Zealand’s largest Fairtrade accredited workplace since 2010. Our tea, coffee and sugar is Fairtrade certified, so farmers in developing countries receive a fair price.


We recycle everything we can, especially our day-to-day waste. We reuse our office furniture and strive to work in a paperless way. We also report on our waste so we know how we’re tracking.


We only travel when it’s necessary, and use video and phone conferencing where possible. We also encourage our staff to use public transport or bike to work to reduce emissions.

The Green Team

Our internal Green Team, consisting of over 300 staff members, advocate our environmentally-friendly initiatives across our locations. 

Carbon neutral

We were the first bank to become carbon neutral, and have been since September 2010. We offset any emissions we can’t avoid by purchasing carbon offsets locally.

Working with our suppliers

We prefer to do business with suppliers that hold similar values to us. As part of the NAB Group, we are committed to our Supplier Sustainability Programme, which aims to mitigate sustainability risks and outlines our expectations for suppliers. For more information, read the NAB Group’s Supplier Sustainability Principles PDF 226KB
