The Demolition Experts

With years of experience, we innovate deconstruction techniques, focusing on diverting waste from landfills. By focusing on reusing, recycling, or repurposing materials, we can reduce our impact on the environment and also contribute to the creation of a more sustainable future

Grün specialises in providing closely aligned business units that work together for our clients.

These are typically for large-scale industrial and commercial organisations and government-funded agencies throughout New Zealand.

Residential Demolition

Residential and Apartment Demolition works are regular workstreams for our business, and we know the process very well, including arranging for disconnections and salvaging recyclable materials. 

Commercial Demolition

We have extensive experience in commercial demolition and have successfully completed projects for our clients.

Our comprehensive service covers all aspects of the project, from planning to site clearance.

We collaborate with clients to ensure satisfaction and take pride in delivering excellent results that meet the highest quality and safety standards.

Industrial Demolition

We have completed specialist projects for industrial clients, including work on Transpower sites and a recent demolition of a 100-year-old steel fabrication site. 

Internal / Manual Demolition

Our leading hand in our internal/manual demolition division is a licensed building practitioner, and we have over 20 years of combined experience in delivering construction and deconstruction services nationwide. We are supportive of timber recycling and landfill diversion practices.
We often work in our clients' buildings, stripping out materials and recycling and separating materials before commencing the demolition stage.
