“They own the site, they own the outcome. That’s why they’re the ones we call.”
Kelvin Burch, Project Manager - Container Terminals Capital, KiwiRail
KiwiRail needed total confidence
With a national network of over 26 bulk diesel sites, KiwiRail relies on robust, compliant fuel infrastructure to keep its rail operations moving. From their contractors, KiwiRail needed consistent service, clear communication, and total confidence that problems would be handled before they became failures.
An extension of the team
Mansfield Group didn’t just retain their position, they raised the standard. From quarterly maintenance and diesel testing to biocide dosing and capital upgrades, Mansfield delivered consistent results with minimal oversight. Their depth of site knowledge meant they could flag issues early and carry out work efficiently. More than a contractor, Mansfield became an operational extension of the KiwiRail team, trusted to represent the standard on-site and deliver what’s needed without delay.
Mansfield services 75% of KiwiRail's fuel sites
Mansfield now services around 75% of KiwiRail’s fuel sites, delivering scheduled maintenance, diesel testing, and issue resolution. They support national capex programmes with site-ready insights and are trusted to maintain high-volume, high-risk assets with minimal disruption. For KiwiRail, Mansfield Group sets the quality bar, with their attention to detail, ownership mindset, and national capability making them a reliable partner in petroleum services.
