Mareanui, a landmark mass timber office development in Tauranga, has been recognised as New Zealand’s leading property project after receiving the highest honour at the 2026 Property Council New Zealand Property Industry Awards. The eight-storey building, which serves as the headquarters for Tauranga City Council, was selected as the overall winner from a competitive field of 133 developments recognised during the industry event held in Auckland.
The project was awarded the prestigious Rider Levett Bucknall Supreme Award, reinforcing the growing influence of timber-based construction within the commercial property sector. The development also secured the Resene Sustainable Building Property Award and the RCP Commercial Office Property Award, making it the most decorated project of the evening.
Developed by Willis Bond and delivered by LT McGuinness, the 10,400-square-metre office building was designed by Warren and Mahoney. Ownership rests with Property Income Fund. The facility has enabled more than 850 Tauranga City Council employees to work from a single location for the first time since 2014.
Industry leaders highlighted the project as an example of successful collaboration. Long-term planning was prioritised. Strong partnerships were established. Shared objectives guided the development process from concept through to completion.
The building stands out for its extensive use of engineered timber. More than 2,700 cubic metres of cross laminated timber and approximately 900 cubic metres of laminated veneer lumber were incorporated into the structure. The timber materials were sourced from Rotorua and Nelson, supporting New Zealand’s domestic forestry and manufacturing sectors.
According to project data, the timber-based design reduces lifecycle carbon emissions by around 60 per cent compared with conventional construction approaches. More than 2,700 tonnes of carbon dioxide are stored within the building’s timber structure. Environmental performance has been further recognised through a 6 Star Green Star Design rating. Additional certification targets include a 5 Star NABERSNZ rating and WELL Gold accreditation.
The development demonstrates how timber can play a larger role in modern commercial construction. It also provides a practical model for cities facing seismic challenges. Wellington and Christchurch have been identified as locations where similar approaches could offer significant benefits.
The structure combines mass timber with steel bracing systems to enhance resistance against seismic activity and strong wind conditions. This hybrid approach allows timber to be used at greater heights while maintaining structural resilience. Industry observers view the project as evidence of how engineered timber technologies continue to evolve.
Operational sustainability was another key consideration. The all-electric building is expected to achieve approximately 70 per cent lower operational carbon emissions. Significant energy efficiencies have been incorporated throughout the design.
The lightweight timber frame also delivered engineering advantages. Foundation loads were reduced by roughly half despite the site’s challenging ground conditions. This contributed to construction efficiencies while supporting the project’s environmental objectives.
Occupant wellbeing was also prioritised. Advanced thermal modelling informed the building envelope and façade design. As a result, natural daylight reaches more than 85 per cent of occupied workspaces. Interior environments were carefully designed to enhance comfort and productivity.
Water conservation measures have been integrated into the development. Rainwater harvesting systems were installed. Potable water consumption is expected to be reduced by around 50 per cent through these initiatives.
Cultural values were embedded throughout the project. Collaboration took place with mana whenua representatives during the design process. Narratives connected to Tauranga Moana have been incorporated into the building’s architecture, interiors and wayfinding systems. Te Ao Māori principles influenced many aspects of the final outcome.
Exposed engineered timber remains a prominent feature throughout the office. Warm interior finishes create a strong biophilic environment. Natural materials are visible across the building’s communal and working spaces.
Project leaders believe the development demonstrates that sustainable timber-rich commercial buildings can remain economically viable when carefully planned. Cost efficiency was maintained. Sustainability targets were achieved. Market demand was successfully captured.
The project also delivered benefits during construction. A total of 135 mass timber piles supplied by Red Stag were utilised, with some extending up to 25 metres in length. Extensive off-site prefabrication was employed. Construction activity was therefore streamlined. Site disruption was reduced. Noise levels were minimised.
Industry judges praised the project for setting a new benchmark for low-carbon commercial property development in New Zealand. Despite its technical complexity, the building was delivered on schedule and below budget expectations. These outcomes further strengthened its standing among the award entries.
The office was fully tenanted and pre-sold upon completion, reflecting strong market confidence in sustainable commercial property. Its success signals growing acceptance of mass timber construction within mainstream real estate development.
As demand for environmentally responsible buildings continues to rise, Mareanui provides a compelling example of how engineered timber can support carbon reduction, occupant wellbeing and long-term commercial performance. The project is now regarded as one of New Zealand’s most significant achievements in sustainable property development and a milestone for the wider timber construction industry.
