A Te Puke petrol station has come third in Z's "Waste Warriors" competition.
The annual nation-wide competition was designed to help Z's service station teams become more aware and motivated to reuse, recycle and compost.
Z Te Puke recycled 83 per cent of their waste.
Z's Sustainability Manager, Gerri Ward, said in a statement when it came to sustainability, long-lasting behavioural change was what was really needed to make a difference.
"At Z we want to do the right thing by New Zealand, so we've made a serious commitment to moving from being part of the problem to being at the heart of solutions around sustainability.
"One of the things we've been focused on has been to cut the waste sent from our service stations to landfill by 70%.
"We found that there were already a few people within our retail service station network who were really taking the lead on engaging site staff to try and attain our 70% reduction goal with gusto."
Over a two month period Z service station sites competed against each other to reduce the amount of waste they send to the landfill.
The competition diverted 191 tonnes of waste away from landfill - the equivalent of two Olympic sized swimming pools full of waste.
