Z Energy is a New Zealand’s largest retail fuel company, providing just under half of New Zealand’s total fuel needs.  Alongside the service station network, Z is also a fuel wholesaler to the Caltex branded service station network along with suppling fuel to retail customers and large commercial customers, airlines, trucking companies and vehicle fleet operators. Z owns and manages nearly 200 Z branded service stations, approximately 160 truck stops and nine bulk fuel storage terminals across Aotearoa New Zealand. Our purpose is 'solving what matters for a moving world' and we aspire to be more than a hydrocarbon related company.  

In 2022, New Zealand’s Marsden Point Oil refinery, responsible for processing and providing approximately 70% of the countries fuel needs, stopped importing and refining crude oil. This required NZ to transition to an import only supply model, triggering the single biggest structural shift in our industry since the Marsden Point refinery started operation some 60 years ago. Given the significance and implications on the country's security of supply, public interest in this change from politicians, customers, staff, and a wide range of other stakeholders was high – keen to see that it was done safely, professionally and with no negative impacts on customers or our economy.

Z’s ‘Pae Tawhiti’ change programme, focused on managing Z's exit from the crude oil supply chain through this transition, while building the capability needed to manage the responsibilities inhouse and position our supply chain for optimisation in the future. The role of Z’s Organisational Development (OD) team was to design and implement the business change management and capability development to ensure Z was first and foremost, ready and able to safely transition to an import terminal model on Day One, stabilise our operations and then optimise Z’s supply chain.
