InterGroup delivers ongoing exterior building and roof cleaning services at Whangārei Hospital as part of Health New Zealand’s long-term asset maintenance programme.
Since 2024, our teams have provided building washing, roof cleaning and associated exterior maintenance services to protect building assets, maintain presentation and support safe operational healthcare environments.
Using specialist washing techniques and high-pressure water blasting, we remove dirt, mould, airborne contaminants and environmental staining that can accelerate deterioration of exterior surfaces. With works taking place throughout a live hospital campus, careful planning and close coordination are essential to ensure patients, staff and visitors can continue to move safely around the site.

Specialist delivery
Selecting the right cleaning methodology is essential to removing contaminants without damaging the underlying substrate or protective coatings.
Our experienced crews use specialist water blasting equipment, rope access techniques and tailored work methodologies to safely clean a wide range of building surfaces while working around the day-to-day operation of the hospital. During routine cleaning, we also identify visible defects or areas of deterioration, allowing maintenance issues to be recognised early before they become more significant.
All works are delivered under strict permit systems, with experienced supervisors overseeing quality, safety and environmental controls throughout the programme.

Protecting assets without interrupting services
Every stage of the programme is carefully planned around hospital operations, with work areas coordinated to minimise disruption to clinical services, pedestrian movements and vehicle access.
To further reduce the impact on the hospital, much of our work is completed using rope access rather than traditional scaffolding. This significantly reduces the site footprint, allows faster mobilisation, and enables our teams to access difficult areas while safely maintaining normal hospital operations.
Long-term value
Over the course of this contract, InterGroup has developed a collaborative working relationship with Health New Zealand, adapting programmes and access methods to suit the changing needs of the hospital while maintaining consistently high standards of delivery.
Our combination of specialist access capability, experienced personnel and carefully planned delivery enables us to maintain critical healthcare facilities safely and efficiently while protecting valuable building assets, extending service life and reducing future maintenance requirements.
