##### INDUSTRIES
## ENERGY & UTILITIES
##### SAFETY & CERTAINTY FOR CRITICAL NETWORKS
New Zealand’s electricity networks rely on confidence in their assets, equipment, and people. DEG provides accredited inspection, calibration, and compliance services to help energy providers and contractors meet regulatory requirements—while keeping safety and uptime front of mind.

###### THE CHALLENGE
###### WHAT WE HEAR MOST OFTEN
##### **PRECISION MATTERS IN ENERGY.**
Electricity networks operate under some of the country's most demanding compliance regimes. Equipment must be safe to use, traceable in its testing history, and ready to defend in front of regulators, governance and your own staff. The cost of getting it wrong — to people, to the network, to the licence to operate — is too high to gamble on a non-accredited provider.
SIX AND TWELVE‑MONTHLY COMPLIANCE CYCLES
HV equipment, EWPs, and live‑line tooling that have to land on time, every time — across regions, across crews, across asset registers that grow every year.
INSULATING PPE AND PROTECTIVE GEAR
Hot sticks, earth sets, and protective gear that need to be tested to recognised standards, with results that hold up to scrutiny — and a record system that can produce evidence in minutes.
AGEING POLE AND POLE‑TOP INFRASTRUCTURE
Where visual inspection alone no longer satisfies risk committees or regulators — but where targeted, defensible NDT is hard to source from a credible provider.
###### HOW DEG HELPS
#### OUR SERVICES FOR ENERGY & UTILITIES.
---
###### Calibration & Compliance
##### HV Testing & Calibration
ISO/IEC 17025 IANZ‑accredited testing of insulating gloves, sleeves, blankets, mats, hot sticks, earth sets, jumpers, proximity testers, phasing and proving devices, and VDDs. Hi‑Pot, VLF, and insulation resistance test set calibration. EWP boom and bucket liner HV testing to ANSI/SIA A92.2. Acoustic emission testing on fibreglass booms to AS 4748.
###### Survey & Inspection
##### EWP & Network Inspection
ISO/IEC 17020 IANZ‑accredited inspection of EWPs (6‑monthly safety inspection certificates, 5 and 10‑year majors to AS 2550.10), cranes, and lifting gear. Targeted NDT of pole‑top steelwork – crossarms, brackets, transformer frames – for fatigue, corrosion, and section loss.
###### Consulting Engineering
##### Structural & Engineering Assessment
Structural and mechanical assessment of substation infrastructure, equipment platforms, and access systems. Producer statements (PS1, PS2, PS4). Incident investigation and expert witness work.
###### WHY DEG
#### WHAT SETS US APART.
###### LARGEST DEDICATED HV COMPLIANCE PROVIDER IN NZ
DEG is one of New Zealand's most established providers of accredited HV equipment testing, supporting a significant proportion of the country's electricity networks and contractors.
###### DUAL IANZ ACCREDITATION
We hold dual IANZ accreditation (ISO/IEC 17025 for the lab and ISO/IEC 17020 for inspection) – taking 18–24 months to obtain and held by very few competitors. One provider covers the gear, the EWPs, and the structural assessments with a single audit trail.
###### COMPLIANCE & DATA MANAGEMENT
Our system captures every test, every interval, every reading – with automated reminders, barcode tracking, and client‑accessible records. When IANZ or your insurer asks for evidence, you have it.
###### INDUSTRY MEMBERSHIPS
Members of the Electricity Engineers’ Association (EEA) and the Lifting Equipment Engineers Association (LEEA). We work to PECPR Regs 1999, the HSWA 2015, and the relevant AS/NZS standards series.
###### CASE STUDY
###### MARLBOROUGH LINES LIMITED
#### ONGOING ACCREDITED TESTING & COMPLIANCE PROGRAMME
Marlborough Lines operates the electricity distribution network across the top of the South Island, including a unique mix of high‑country and coastal lines, running through some of the most demanding terrain in the country. DEG provides ongoing accredited testing of insulating PPE, EWP HV testing and certification, and field support — a single point of contact for compliance work that previously required multiple suppliers.
“We are able to offer a single point of contact for compliance work that previously required multiple suppliers.”
