The upgrade was designed to increase gas injection and withdrawal rates from 35 to 65 terajoules per day. Verbrec was engaged to provide multidisciplinary support across design, procurement and commissioning, helping the facility meet its expanded performance targets safely and efficiently.
65 TJ/day
Expanded gas injection and withdrawal capacity.
Full lifecycle
Support delivered from concept through to commissioning.
Brownfield integration
Upgrades delivered with minimal disruption to live operations.
Working within an integrated team structure, Verbrec helped maintain alignment between design, execution and operational requirements throughout the upgrade. This whole-of-project involvement supported a smoother transition from early planning through to plant handover, while keeping the focus on performance, safety and delivery certainty.
Verbrec applied its brownfield engineering experience to connect new systems into the existing facility while maintaining operational continuity. The work required detailed interface planning, strong safety protocols and close coordination with site teams to manage risk and ensure the upgrade could be delivered efficiently within an operating asset environment.
With the upgrade complete, the facility now provides significantly greater flexibility to the energy system it supports. By doubling capacity, the site is better positioned to balance daily and seasonal demand, enabling faster and more flexible access to stored gas when it is needed most. The result is a stronger, more resilient role for gas storage within New Zealand’s broader energy mix.
This upgrade strengthens New Zealand’s energy resilience by enabling faster, more flexible access to stored gas and helping ensure long-term stability across the network.
