Infrastructure Decommissioning

We specialise in the safe and compliant removal of redundant energy assets in New Zealand.

​Decommissioning work is highly specialised.

We are here to work with you every step of the way throughout the process of your decommissioning projects. We make the removal of redundant material simple and easy, with safety, transparency and a professional attitude throughout the process.

At GMR Energy our service can be as simple as pickups from your depots around the country. Or contact us early on to scope and price the entire substation decommissioning works, including bulk removal of cables, transformers and switchgear.

We have thorough procedures in place for identifying and managing hazards and disposing of decommissioned assets in an environmentally responsible manner.

Our Service To You

We offer the safe and efficient removal of all redundant equipment, and we can project manage your entire decommissioning project.

Our service includes pricing the removal of all associated redundant equipment, physically dismantling it and loading assets onto transporters on site. We provide full methodologies, JSA’s and engage approved third party contractors, alongside NZQA qualified staff, where needed.

With over 30 years in the energy industry, our highly experienced staff have extensive knowledge of substation environments around the country. They understand the local conditions, hazards and industry compliance requirements.

Bring us your old mags and we’ll pay to take them off your hands.

Safety First

Smooth decommissioning projects depend on safety first. Prior to commencing the removal of any assets, all removed equipment is identified and proven to be de-energised and disconnected from any supply sources.

We ensure that all identified hazardous waste is handled by an approved or correctly trained person. Where applicable, traffic management is provided, to ensure public and staff safety.

Complete Transparency

​All salvageable scrap materials are weighed and the docket is forwarded to the client within 48 hours of the asset being removed.

Project Completion

All waste material is removed from site and the site is swept clean. Where required, our service can include the reinstatement of floors or access ways.

Full Documentation

Upon completion of works at each site, a report is provided with photos and details on the new current condition of the substation.

We can manage the full project for you and dispose of the whole network associated with the particular piece of equipment that you need decommissioning, from the overheads to the underground cables.

We operate with full transparency

We provide written statements of compliance and destruction certificates to prove your assets have been disposed of in the correct manner.


Health & Safety Procedures

Health and safety compliance is at the forefront of our operations, with the following in place for every project.

Risk Procedures

Different organisations typically follow specific procedures for managing their unique environmental risks. We incorporate each organisation’s own environmental risk procedures into our own stringent risk management procedures.

Risk Register

We begin any project by first identifying hazards through a Risk Register Assessment. This is developed in conjunction with our client to ensure any additional health and safety procedures at an organisation level are also included in the Register.

Daily Hazard ID forms are produced every day and we have an onsite diary.

Job Safety Analysis & Reporting

Paperwork is produced around methodologies, along with Job Safety Analysis Sheets. All risks associated with a project are listed in detail, along with any associated risks relating to the actual work being undertaken.

Environmental Risk

We take environmental risk extremely seriously, from the initial onsite work, to post-decommission and disposal of materials. We make sure decommissioned products are disposed of in an environmentally responsible way.

MSD Forms

Material Safety Data Sheets (MSD forms) also form part of our extensive job packs. Every day we have a site meeting before we start the job, where we list all hazards and tick every box. We make sure that JSAs have been read by every person in the work party and that every person involved in the project has a full and clear understanding of all health and safety requirements.

Photographic Evidence is Provided

Photos are taken before and after site decommissioning and included in the job folder.

A decommissioning project accumulates an extensive amount of documented information because everything related to health and safety and site compliance is recorded. The contents of the project folder are readily available to our clients any time they wish to see it. Upon completion of the project, a full copy of all documentation is provided to ensure our client is fully compliant and covered for audit.


Meet our Decommissioning Manager

Julian O’Connell



GMR Metal Recyclers company founder and managing director has spent over 30 year in the scrap metal industry.

After selling GMR to Phoenix Metalman in February 2022, Julian decided to continue his focus within the industry on delivering core de-commissioning services to the energy and infrastructure sectors, assisted by Phoenix Metalman’s nationwide footprint.

Phoenix Metalman are honoured to be given the opportunity to respectfully continue the ground work laid in the region to recycle 99% of everything received, from sub stations, to factory/plant/equipment removal and more.

Recent Work

Wellington Trolley Bus Network

GMR was project manager for the decommissioning of substations that served the Wellington overhead trolley bus network. The overhead network was completely removed by June 2018 and the first substation was removed that November. The project involved 17 sites in total and work was completed in late 2019.

Gisborne Substation

Tuai in the Waikaremoana

Remote sites have their own challenges. You can’t afford to forget anything. When you’re two hours away from the nearest rental shop, you need to be highly organised and well planned. This project is currently underway and the work pack is being developed. Decommissioning these four transformers will take a solid week for a team of four to five people.

We continually invest in the only the best specialist equipment, ​ensuring safety and compliance at all times.

We can handle any scale of decommission required, from 2-250 ton transformers.
