This procurement offers an opportunity to deliver a high-profile, sustainability-led infrastructure project for Auckland Transport within a critical operational rail facility. Successful tenderers will play a direct role in supporting Auckland’s decarbonisation objectives by delivering a large-scale rooftop solar installation integrated with proactive asset renewals.

The project brings together renewable energy delivery and commercial roofing works under a single contract, providing scope for contractors to demonstrate end-to-end capability, strong programme management, and safe delivery in a live environment. With detailed designs completed, key approvals in place, and a clear scope defined, the project offers certainty of requirements and a well-structured delivery pathway.

Tenderers will have the opportunity to:
• Contribute to a flagship public sector sustainability initiative with long-term environmental and operational benefits
• Showcase technical expertise in solar PV, roofing renewals, and complex site delivery
• Partner with a major public transport asset owner committed to ethical procurement, ESG outcomes, and long-term value
• Deliver works that make a measurable difference to emissions reduction, asset resilience, and public infrastructure performance
Auckland Transport is seeking capable delivery partners who value quality, safety, and sustainability, and who are motivated to help shape the future of resilient, low-carbon transport infrastructure in Tāmaki Makaurau.

The scope includes the turnkey installation of a ~390 kWp rooftop solar PV system, together with roof recoating and replacement of deteriorated skylights, delivered under a single NZS 3910 contract. The roof renewal works will be undertaken to improve safety, extend asset life, and ensure the roof is fit for purpose prior to solar installation.

This project forms part of AT’s wider decarbonisation and sustainability programme and directly supports its target to reduce operational greenhouse gas emissions by 50% by 2031. By integrating renewable energy infrastructure with proactive asset renewals, the project delivers long‑term operational, safety, and environmental benefits.
