Almost a fifth of the country's greenhouse gas emissions come from transport, and as we're one of New Zealand's major fuel companies, we know the products we sell contribute to this.
At Z, we’re committed to helping our customers reduce carbon emissions from the fuels we sell, and making biodiesel available is the single biggest step we can take towards that. Biodiesel is made from renewable resources, and is a more sustainable and cleaner burning alternative to ordinary diesel. While relatively new for New Zealand, biodiesel is commonly used across Europe and many other countries, and has been for nearly 20 years.
Our biodiesel production plant in Wiri, Auckland is the result of more than four years of careful planning and design, enabling us to bring a high quality biodiesel, Z Bio D, to New Zealand. It wouldn’t have been possible without the help and commitment from some progressive New Zealand businesses. It will be available in parts of the North Island from early 2017.
The biodiesel manufacturing process uses proven technology and best practice to produce a high quality product.
Switching to Z Bio D is an easy way for you to make a difference.
When compared to ordinary diesel, using Z Bio D can reduce your carbon emissions by almost 4% with every fill* (PDF 53kb). It’s a small step we can all take that adds up to a giant stride for NZ.
Biodiesel burns more cleanly than ordinary diesel, creating less of the particulate matter in exhaust emissions that contribute to air pollution.
Z Bio D is made right here in Wiri, Auckland. Producing biodiesel in New Zealand reduces our reliance on imported fossil fuels and creates local jobs.
Z Bio D is made from locally sourced tallow, an inedible by-product of the meat industry, which doesn’t compete with food production.
Z Bio D is a high quality, sustainable biodiesel that helps New Zealand's diesel community reduce emissions and reduce our environmental impact.
Z’s B100 diesel will meet the New Zealand and European biodiesel standard – where biodiesel has been used for many years.
Our standard Z Bio D is made from up to 5% biodiesel blended with ordinary diesel (called a B5 blend) that meets the same NZ fuel specifications as ordinary diesel.
As B5 is classified as ordinary diesel under the New Zealand fuel specifications, there are generally no special engine modifications or vehicle manufacturer permissions required.
The Engine Manufacturers Association (EMA), an international member body representing internal combustion engine makers, has issued a technical position statement on the use of biofuels in diesel engines. The EMA does not expect B5 biodiesel to cause any engine problems, so long as the B100 used for blending meets the European biodiesel standard (EN14214). Z's B100 biodiesel meets this standard.
Compared to ordinary diesel, Z Bio D has better lubricity and can reduce friction and wear on fuel system components. This means, if properly monitored and maintained, using Z Bio D may help to extend the life of diesel motor engines.

Engine compatibility recommendations
Initially Z Bio D B5 will be available in the Auckland, Bay of Plenty and Waikato regions, where it will replace ordinary diesel in Z's service stations, truck stops, and bulk deliveries. We're hoping to make it available to all of New Zealand eventually.
The development of Z Bio D wouldn't have been possible without the support of our key customers.
