They say fortune favours the bold, but in energy, it’s grit, consistency, innovation, and care that stand the test of time. MB Century’s story is proof of that. Born from New Zealand’s pioneering spirit, in its inception has the Ministry of Works and Development, the company helped deliver the world’s first wet steam geothermal power station at Wairakei, a milestone that sparked both a global industry and has held a decades-long reputation for doing things right.
Seventy-five years on, MB Century has grown from a government department into New Zealand’s most trusted renewable energy partner. Their expertise spans geothermal, hydro, and hydrogen, yet the core focus remains simple: helping clients get the most from their assets safely, efficiently, and sustainably.
“Trust has always been our compass. We don’t chase headlines or shortcuts; we build relationships that last. From Taupō to Jakarta, we’re known for being down-to-earth, reliable, and deeply proud of the work we deliver, quietly shaping the future of clean energy across New Zealand and the Asia-Pacific.
A Mindset of Precision and Partnership
For MB Century, expertise across geothermal, hydro, and hydrogen energy is only the beginning. What truly defines the company is not just its technical capability, but the people behind it. The engineers, drillers, designers, and workshop teams who have built and refined solutions for over 75 years. Their collective knowledge, passed down and grown through generations, continues to shape how MB Century delivers smarter, safer, and more sustainable outcomes.
Precision, innovation, and reliability remain at the core, yet the real distinction lies in how these qualities are applied, with care, collaboration, and purpose.
Rig 32, one of the safest and most advanced geothermal rigs in the Asia-Pacific, exemplifies that commitment. Alongside it, a suite of in-house wireline tools delivers industry-leading data, giving partners clarity and confidence in every decision.
But tools and technology are only part of the story. Every solution is guided by mindset, no cookie-cutter answers, just designs that fit the client, the asset, and the future they’re building toward. From drilling, feasibility studies, and FEED to fabrication, machining, coatings, and field operations, MB Century offers an end-to-end service built on experience, curiosity, and craftsmanship. It’s this people-powered approach that keeps clients’ assets performing at their best and ensures the next generation of energy specialists can carry that legacy forward.
Because of this legacy, clients know the expertise they receive from MB Century is not only proven, it’s unmatched anywhere in the world.
Partnerships That Endure
In high-stakes energy projects, trust isn’t optional; it’s the foundation. MB Century Ltd cultivates it by being transparent, delivering on promises, and staying alongside clients long after a project is complete. In New Zealand, this approach has fostered decades-long partnerships with leading generators, providing operator maintenance work that ensures assets remain optimized and reliable. Internationally, the same philosophy applies: building strong local relationships that complement technical delivery, earning confidence through consistent performance and integrity.
MB Century Ltd’s culture revolves around clarity, commitment, and putting safety and quality at the core. Complex projects demand more than contractors; they require partners who listen, adapt, and stand shoulder-to-shoulder at every stage. Many relationships span decades because clients know the company will be there long after the ribbon is cut, ensuring assets continue to perform at their peak. “If there’s a better way or a safer path, we’ll say it.” That honesty is central to the trust MB Century Ltd has earned.
Challenges are inevitable. Volatility in global energy markets, extending asset lifecycles beyond design, and entering new markets like Indonesia have tested the team. MB Century Ltd meets these hurdles by innovating in coatings, machining, and fabrication, while forming strong local partnerships, showing that capability and genuine commitment go hand in hand.
Collaboration that Shapes Energy’s Future
At MB Century, the team isn’t just a collection of skilled professionals; it’s the pulse that drives every project forward. The culture thrives on one principle: “the work speaks louder than the individual.” Humility and accountability are the expectation; egos are left at the door, replaced by shared goals and a relentless focus on excellence. From welding in workshops to drilling the next geothermal well, every team member knows they are part of something far bigger, powering safer, cleaner, and more efficient energy for communities.
Engagement comes naturally when people see the impact of their work. International opportunities, training pathways, and celebrated successes keep the team inspired, while psychological safety ensures every idea has a voice. The results are tangible. At Roxburgh Hydropower Station, New Zealand’s oldest operating hydro station, MB Century Ltd’s turbine upgrade extended its life and boosted efficiency, safeguarding power for thousands. In Indonesia, advanced geothermal well surveillance set a new standard for optimization. At Te Ahi O Maui Geothermal Station, early agreement on process design allowed construction to proceed without performance guarantees, reducing risk and cost. These projects prove that MB Century Ltd delivers more than solutions; they deliver trust, future-proofed assets, and enduring impact.
Legacy, Innovation, and Global Impact
From pioneering New Zealand’s geothermal industry to creating well logging tools that perform in the most extreme environments, MB Century Ltd’s legacy is etched in decades of milestones. In November 2015, the Reservoir Engineering team completed a once-in-a-decade replacement of anti-scalant tubing, quenching wells, upgrading wellhead assemblies, and installing new control systems, demonstrating precision, coordination, and decades of accumulated expertise. In October 2025, the team will repeat these surveys, continuing a long-standing connection with this unique geothermal field. Meanwhile, the Philippines-based wireline team, active since 2008, has extended its client partnership until 2030, conducting PTS, HTCC-EM, and MF surveys across multiple geothermal sites.
MB Century Ltd’s ingenuity stretches back 75 years, beginning with the vertical cyclone separator of the 1960s, a design that remains in widespread use today. Over the decades, MB Century Ltd has also developed and operated Pressure, Temperature & Spinner systems, along with specialist casing integrity tools deployed across Indonesia, Papua New Guinea, and the Philippines. Milestones such as drilling over 100km with Rig 27 and Rig 32 showcase the company’s technical mastery paired with strong client relationships. “Our vision isn’t just about growth, it’s about building on 75 years of proven delivery to power the next 75 across Asia-Pacific,” a principle that guides every project. With strategic expansion into Indonesia and Taiwan, alongside hydrogen initiatives, MB Century Ltd is positioned to accelerate energy transitions globally, delivering safe, sustainable, and efficient solutions while keeping its promise as the trusted partner who makes energy happen.
