Engineering the transition for Australasia’s most critical sectors.
Stop leaving your energy and carbon goals on paper. We provide the sector-specific technical strategy and engineering delivery required to future-proof your operations across New Zealand and Australia.
A partner who understands your operational reality.
Many advisory firms can write a high-level sustainability report, but very few understand the mechanical and financial nuances of your specific sector.
Transitioning mission-critical infrastructure requires more than just "advice"—it requires a partner who knows how to manage the
1,900 MW peak demand challenge without risking your service delivery or daily throughput. At DETA, we bridge the gap between boardroom ESG targets and operational realities. We know that for
71% of operators, production and continuity are the absolute priorities. Whether you are managing a national energy network, a regional healthcare complex, or a high-output manufacturing site, we engineer flexibility and efficiency that respects your specific constraints.
Sectors We Support
Dairy Processing
We lead the way in process heat electrification. We engineer the high-temperature heat pumps and thermal storage systems required to phase out fossil fuels in high-potential flexibility regions like Waikato, Taranaki, and Canterbury.
Meat Processing
We specialise in high-capacity refrigeration and wastewater heat recovery. By identifying storable and shiftable loads, we help meat processors avoid volatile $500/MWh peak prices without compromising the cold chain.
Food & Beverage
From breweries to fruit processing, we deploy debottlenecking and heat recovery strategies. The 2026 national energy report identifies food processing as a top-tier contributor to "flattening the curve" for the national grid.
Industrial & Manufacturing
We manage the complex energy needs of metals, forestry, and heavy manufacturing. We help sites in the Bay of Plenty and Southland implement large-scale battery storage to arbitrage grid prices and improve resilience.

Infrastructure
We provide the technical strategy required to avoid costly grid and GXP upgrades. Our work helps secure the $3 billion in avoided infrastructure costs identified in recent national research.

Commercial Buildings
Wellington and Auckland offices are massive untapped sources of flexibility. We provide the HVAC-led load shifting and investment-grade energy audits required to reduce utility waste and ensure mandatory ESG compliance.
Local & Central Government
We partner with agencies like EECA to lead regional energy transition (RETA) and public sector decarbonisation. We translate policy goals into physical, engineering-led roadmaps for public assets.
Healthcare
We deliver hospital-wide energy audits and efficiency improvements. Our engineers identify actionable energy savings that protect critical care and patient comfort while meeting ambitious public sector carbon targets.
