DELTA BOX

The new standard in temporary power supply

Temporary power shouldn’t be hard work. Our Delta Box is a purpose-built Builder’s Temporary Supply (BTS) unit designed to make life easier on construction sites. It's safe, compliant, reliable, and ready to go when you are. We’ve taken the complexity out of your temporary power supply, so your team can stay focused on the job at hand.

Why choose our Delta Box?

One provider. One solution. No stress.

Many temporary supply setups involve multiple contractors, unclear responsibilities, and unpredictable costs. Our Delta Box eliminates fragmentation by providing a complete end-to-end service.

Hassle-free installation

Our teams manage installation, so you don’t have to. We get your site powered up quickly, correctly, and without major disruption.

100% compliance, delivered by experts

Each unit is built to the standards expected of New Zealand’s utility sector. With decades of electrical experience behind us, Delta ensures that every installation meets the latest safety and compliance requirements.

Clear, predictable pricing

A flat rate means you know exactly what you’re paying for. No hidden fees, no unexpected extras, and no time lost chasing multiple contractors.

Reliable power, built for site conditions

Our Delta Box is designed to handle the realities of construction work. The unit is robust, secure, and engineered for consistent outdoor performance - ensuring that tools, equipment, and site facilities run smoothly every day.

Sustainable by design

We understand that responsible construction goes further than timelines and budgets. Our Delta Box is not only manufactured using recycled materials, but is also recyclable at end-of-life. It’s a solution that supports both project and environmental performance.

A partner you can trust

Delta has served New Zealand communities for decades. We manage, maintain and protect critical infrastructure every day, and we bring that same care to every Delta Box we deliver. When you choose us, you’re backed by a local team that understands your industry and the expectations that come with it, as a trusted long-term partner.

Support you can count on

Our Delta Box is built for reliability, but construction sites can be unpredictable. If you need support, we’re only ever a phone call away. Our team responds quickly, resolves issues directly, and takes ownership from the moment you contact us. Support isn’t an add-on. It’s part of our commitment to keeping your project moving safely and efficiently.
