We manage a wide range of properties on behalf of the Crown and client agencies, including former prisons, hospitals, schools, as well as residential and commercial properties.

Some of these properties are earmarked for Treaty settlement. In some cases, part of our role in preparing a property for Treaty settlement can include clearing infrastructure, remediating the land, managing contaminants in the soil, and mitigating hazards on site.

Below are some of the key projects we are currently working on across the Crown property portfolio.

Former Tokanui Psychiatric Hospital

We are responsible for overseeing the demolition and disposal of the former Tokanui Psychiatric Hospital, south of Te Awamutu.

The site is part of a potential Treaty settlement with Ngāti Maniapoto.

Funding has been secured to demolish the buildings and remediate sections of the 80-hectare site.

We are working closely with Maniapoto, mana whenua and the Office for Māori Crown Relations, Te Arawhiti, to inform the level of works to take place at the site.

Demolition is expected to begin in 2023 and take approximately four years to complete.

Former Masterton Hospital

We are managing the demolition of the former Masterton hospital.

The site is part of a Treaty settlement with Ngāti Kahungunu.

Preliminary work started in November 2020, and our current focus is on salvaging as much material as possible from the 26 buildings to be demolished.

We have come up with a plan that will see around 2500 cubic metres – equivalent to the volume of an Olympic sized swimming pool – of material diverted from landfill.

We are also using a range of measures to mitigate any impact on the neighbouring Wairarapa Hospital and Masterton Medical Centre. This includes carrying the demolition out in stages, as well as using specialist equipment to dampen down dust and acoustic barriers.

The demolition is underway and is expected to be completed by late 2022.

Former Barrett St Hospital

We are managing the former Barrett Street hospital, in central New Plymouth, on behalf of the Crown.

The site is part of a Treaty settlement with Te Atiawa. We oversaw the demolition and removal of 14 structures and their supporting service tunnels in 2018.

Further works are required on site including the removal of stockpiles, auxiliary buildings, swimming pool and retaining walls.

We are currenlty working with New Plymouth District Council and Te Atiawa for a resource consent to carry out this remaining work.

This work is expected to get underway early 2022.

Watts Peninsula

We are responsible for managing Watts Peninsula on behalf of the Crown.

We have a range of measures in place to minimise hazards on the site, as we are aware it is popular destination for recreational purposes.
