Waikato Steel Manufacturing Project Approved Through Fast-track Process
A new structural steel manufacturing plant planned for Hampton Downs in Waikato has been approved under New Zealand’s Fast-track process, marking a further step in strengthening domestic supply chains for major infrastructure. The project, proposed by National Green Steel Limited, is intended to expand local manufacturing capacity, reduce reliance on imported steel, and increase the reuse of scrap metal within New Zealand. The decision was announced on 18 March 2026 following consideration by an expert panel.
The approval follows an application lodged in July 2025 and took around five months after the expert panel process commenced. According to the official government release, the project is the 13th to be approved under the Fast-track Approvals Act and the first infrastructure project within the programme to focus on steel manufacturing.
Building local capacity for infrastructure delivery
Infrastructure Minister Chris Bishop said the project aligns with the government’s wider objective of accelerating infrastructure delivery while reinforcing domestic supply chains. He highlighted the role of local manufacturing in addressing long-standing constraints on infrastructure development, including dependence on imported construction materials.
“New Zealand has a major infrastructure deficit. We need to deliver infrastructure faster, and we need the supply chains to back that up. A project like Green Steel can do both, building local manufacturing capacity and help provide material for a range of developments.” — Mr Bishop
The plant is expected to process approximately 200,000 tonnes of recycled steel each year. By doing so, it will reduce both the volume of structural steel imports and the amount of scrap steel currently exported offshore for processing.
Recycling scrap steel within New Zealand
National Green Steel already operates metal collection yards in Auckland, Wellington, Hamilton, Putāruru and Christchurch. These facilities recover steel from end-of-life vehicles, sheet metal and structural beams, materials that are currently largely exported rather than reused domestically.
“New Zealand does not currently re-use steel – most of our scrap metal is exported. This new plant will mean we can recycle and manufacture structural steel right here in New Zealand, using material sourced from across the country.” — Mr Jones
The project is expected to create around 200 skilled jobs in the Waikato region, contributing to regional economic development alongside its national infrastructure role.
Lower-emissions production and electrification
The plant will use electric arc furnace technology to produce structural steel. This method has a lower carbon footprint than existing steel production approaches used in New Zealand, reflecting a broader shift towards electrification within heavy industry.
“The project will use electric arc furnace technology to produce high-quality structural steel with a lower carbon footprint compared to current steel production methods used in New Zealand. This proposal shows the sector are willing to make the investments needed to electrify.” — Mr Watts
The emphasis on electrification and sustainability sits alongside other public-sector efforts to modernise infrastructure and services, including initiatives where smart technologies are being applied across public services and where long-term planning is supporting more sustainable infrastructure development.
Fast-track programme context
As of 12 March 2026, 21 projects had expert panels appointed under the Fast-track process, with 49 projects progressing through the system and 149 listed in Schedule 2 of the Fast-track Approvals Act as eligible to apply. On average, decisions on substantive applications have taken 129 working days from the point an application is deemed complete and in scope.
