Christ Church Cathedral stabilisation
Consultant: Holmes and Naylor Love
Client: Christ Church Cathedral Reinstatement
Christ Church Cathedral has high cultural and spiritual significance for its former role as the cathedral church of the Anglican diocese in Canterbury, for its civic role as a venue for important cultural events, and as the physical and metaphorical heart of Ōtautahi Christchurch.
The devastating earthquakes of 2011 caused significant damage to this historic, much-loved Cathedral – a national icon in Aotearoa New Zealand. The west façade facing Cathedral Square collapsed, the tower was badly damaged and collapsed, and destruction was widespread throughout the building.
In 2019, Holmes and Naylor Love were appointed to provide structural engineering and construction consultant services, for the project’s stabilisation phase.
Stabilisation of the cathedral presented significant technical engineering, construction and health and safety challenges given the site constraints, biohazards and the badly damaged structure. At the same time the work had to preserve the historical character and facilitate the restoration phase.
Holmes and Naylor Love are recognised for the expertise, commitment and a deep understanding of its structural challenges that had to be addressed to set up the cathedral for the project’s reinstatement phase.
Constellation Brands press building and front-end automation
Client: Constellation Brands New Zealand
Constellation Brands iconic Kim Crawford Winery in Blenheim needed a major processing capacity expansion to meet demand for its Kim Crawford Sauvignon Blanc wine worldwide. Achieving this required a step-change in production capacity with automation and future-proofing required and reliability risk reduced.
Aurecon took on a high-risk project to completely reconstruct and automate the front-end processing capacity of a 30,000 tonne winery to 40,000 tonnes per year. Construction had to be undertaken between vintages. Working collaboratively with the client, suppliers and the construction team resulted in a successful project, on time and within budget. In the process the team improved the health and safety, environmental impact, working conditions, and process efficiency.
Using a fast, nimble, hybrid design and construction process resulted in the new facilities being commissioned and ready for the 2022 harvest when the winery processed 42,000 tonnes of grapes through the new plant without any problems.
Aurecon is recogised for outstanding client centric collaborative approach, its technical expertise and its management of risk.
Lime Kiln failure and emergency repair
Consultant: Index Engineering
Client: Oji Fibre Solutions - Kinleith Mill
Oji Fibre Solutions is a leader in pulp, paper and packaging production in New Zealand. Index Engineering was engaged as lead mechanical engineer when the OjiFS Kinleith Lime Kiln failed. The lime kiln suffered a catastrophic failure: it overheated, refractory bricks burned and collapsed into the kiln, and the lime kiln carbon steel shell corkscrewed. The lower part of the kiln slumped downwards.
There was enormous pressure from OjiFS management to resolve the kiln failure in a cost-effective and safe manner but within an urgent timeframe. Overseas advise indicated that the repair was likely to take months. Compounding the situation, the country was in the middle of its Covid response, meaning overseas experts from the kiln supplier could not be easily brought to New Zealand.
Index Engineering is recognised for the leadership and co-ordination it provided, its technical expertise and guidance, responsiveness, commitment and its collaboration with the client, stakeholders and multiple personnel. It is a testament to its commitment and expertise that the repairs were completed in 3.5 weeks. Index is acknowledged for the excellence in delivery and execution of the consulting service.

St James Theatre and Ballet Building
Client: Wellington City Council
Wellington’s iconic 1912 St James Theatre and Ballet Building have been sympathetically strengthened and upgraded, bringing one of the region’s most important arts venues back into use, and revitalising Wellington’s Courtenay Place arts and entertainment heart.
Deconstruction of the building uncovered numerous unwelcome discoveries from the 1990s seismic retrofit. Multiple times when the interface was exposed, the as-built construction was not as it was supposed to be, necessitating significant redesign and resequencing of the construction works programme. Heritage theatre buildings are notorious for their poor climate control systems, and the St James Theatre was no different presenting complex challenges for Beca’s HVAC team.
Beca is recognised for the architectural sympathy within which the structural strengthening was undertaken, the delivery of an enhanced level of user comfort which is world leading, and the responsive, collaborative leadership it provided. It’s a testament to Beca’s commitment that the project was completed on time for opening night.

Auckland Harbour Bridge emergency repairs
Client: Waka Kotahi NZ Transport Agency
The Auckland Harbour Bridge is one of New Zealand’s most critical transport links. On 18 September 2020, a freak 127km/hr wind gust caused two trucks travelling over the Auckland Harbour Bridge to topple over, causing critical structural damage to the historical truss bridge and a significant reduction in its capacity to carry vehicles. The four central lanes were immediately closed to ensure the safety of bridge users, leading to gridlock across Auckland’s motorway network. With more than 170,000 vehicles traversing the bridge each day, the economic and social impact required an urgent response.
Waka Kotahi called upon its trusted advisors, Beca and the Auckland System Management alliance to get the bridge back into safe operation as soon as possible, anticipating a four-week programme and social disruption costs of $40 million.
Beca leveraged its 25-year knowledge of the bridge, advanced design tools, and trusted, established relationships with the client and construction partners to help deliver the repairs quickly, reliably and accurately during limited night-time closures.
Beca is recognised for its seamless collaboration in design, fabrication and installation which delivered an elegant, structurally-sound solution in 18 days.
Kauri Dieback mitigation in Northland's walking tracks
Consultant: Frame Group
Client: Northland Regional Council
An Aotearoa icon, kauri are among the world's mightiest trees, growing to over 50m tall, with trunk girths up to 16m, and living for more than 2,000 years. Kauri forests once covered 1.2 million hectares from the Far North of Northland to Te Kauri, near Kawhia and were common when the first people arrived around 1,000 years ago.
Phytophthora agathidicida (PA) is a fungus-type pathogen which damages the tree’s root system. It reduces the tree’s ability to take water and nutrients from the soil and transport it throughout the plant.
There is no known cure, but we can help reduce its spread by avoiding any movement of soil around the roots of trees. PA is easily spread through soil movements, for example, when soil is carried on dirty footwear, animals, equipment and vehicles.
Frame Group is recognised for the leadership, collaboration and consultation undertaken in developing the National Kauri Dieback Track Infrastructure Guidelines, managing and delivering track upgrades and training and upskilling communities in best practice techniques for infrastructure maintenance and upgrading.
Speeding up electrification – the ElectroNet transportable switchroom journey
Client: Transpower New Zealand
Transpower’s Whakamana i Te Mauri Hiko report predicts an approximately 70% growth in annual electrical energy demand from now to 2050 as part of achieving New Zealand’s goal of net zero carbon. Significant additional electrical energy will be required for electrification of process heat, production of green hydrogen and the electrification of our transport fleet. Coupled with skill shortages, inflation and increasing capital costs, the need to speed up project delivery through innovation is more critical than ever.
Transpower is facing significant challenges with commissioning projects associated with replacing 33,000 volt outdoor switchyards with indoor switchboards, within acceptable timeframes.
To speed up these vital projects, ElectroNet lead a collaborative initiative with Transpower to develop a transportable switchroom, the Modular Switchroom Solution (MOSS). Delivering a solution required an “outside the box” approach which challenged how things were done.
Electronet is recognised for working collaboratively with its client and key stakeholders, challenging the historical construction and delivery model to develop a modular solution that dramatically cuts site construction time.
Wellington network operational readiness for Transmission Gully opening
Client: Waka Kotahi NZ Transport Agency
Te Aranui o Te Rangihaeata – Transmission Gully motorway (SH1) opened in March 2022 providing a safe, modern and reliable route in and out of Wellington.
Originally conceived in the early 1900s, it aimed to transform the Wellington transport network by reducing the number of fatal and serious injury crashes, increasing economic benefits and providing a more reliable and safer journey.
As construction neared completion, the Wellington transport network was about to experience a transformational change in transport connectivity. It was essential to ensure that the transport network was ready for transition and the wider network integration. Waka Kotahi appointed Aurecon to support with preparing the stakeholders and transport network users for this transition
Aurecon is recognised for its ground-breaking development and delivery of a successful suite of services, including transport network performance assessments, stakeholder engagement, operational planning, and physical intervention procedures.

Kauri Dieback mitigation in Northland's walking tracks
Delivery team: Frame Group, Northland Regional Council, Ministry for Primary Industries and Department of Conservation
An Aotearoa icon, kauri are among the world's mightiest trees. Kauri forests once covered 1.2 million hectares and were common when the first people arrived around 1,000 years ago. They are now under threat.
Kauri Dieback is a fungus-type pathogen which damages the tree’s root system, crippling the tree’s ability to take and transport water and nutrients throughout the plant.
There is no known cure and this fungus serves as a death sentence to this revered and iconic species. Its spread can be reduced by avoiding any movement of soil around the roots of trees, often spread on dirty footwear, animals, equipment and vehicles.
The Sustainability Award is given to Northland Regional Council, Ministry of Primary Industries, Department of Conservation and Frame Group in recognition of their initiatives, commitment and engagement with stakeholders to saving our kauri forests.
The collaboration between these organisations was key in establishing world leading guidance on the management and mitigation of Kauri Dieback.
