Where we are

Operating in Aotearoa since 2017, WGA (Wallbridge Gilbert Aztec) brings local expertise backed by an international reputation built over 40 years. 

We understand the Aotearoa / New Zealand market, and our clients are serviced from our Tāmaki Makaurau (Auckland), Kirikiriroa (Hamilton) and Ōtautahi (Christchurch) offices, supported by the scale and certainty of WGA’s Australian operations which guarantees the same quality performance each and every time. 

Across the country, our team of water scientists are renowned for delivering advice on Managed Aquifer Recharge, integrated water management, hydrology, hydrogeology, water quality, and geochemistry. 

Our water expertise is expanding to offer holistic civil engineering services across the whole water cycle. 

With a local capability in Ports and Marine, our structural engineering covers marine infrastructure projects ranging from pile and deck piers to large wharf infrastructure projects. 

We don’t believe that one size fits all. Instead, we take time to tailor our services to our market with a client focus approach and a commitment to safety and quality, meaning your projects are in safe hands no matter the complexity.
