About Us

Cook | Costello

Cook Costello is a New Zealand owned medium size company of Consulting Engineers with more than 40 years of Civil/Structural Engineering and specialist geotechnical service provision, also specialising in land surveying and consents. Cook Costello operates from the cities of Whangarei, Auckland, Wellington and Christchurch and serves national and international clients. Since September 2010 we have had a dedicated team of engineers and technicians on the ground in Christchurch, Canterbury assisting with the Kaikoura and Canterbury recovery and construction projects.

Working as a collective team means we share information on the same systems in real time and are efficient at project managing and collectively finding the solutions that best fit our client’s requirements. This results in enhanced timelines and quality product/returns for our clients.


Working from an International Best Practice perspective we have consistently identified that excellent data collection on the ground is essential in identifying information for future foundations, structural and infrastructure design. Utilising a ground up approach and applying internationally recognised expertise in determining the impact of settlement (vertical displacement), lateral spreading (horizontal displacement) and liquefaction provides surety for the end product. We facilitate and strongly encourage the use of CPT (Cone Penetration Testing) analysis.

For these reasons we have a close relationship with GEOCIVIL Ltd, an IANZ accredited laboratory. Geocivil is so committed to providing all our clients with the best information for their project that they have imported specialised CPT equipment for ground assessments to support the best possible engineering outcomes. Geocivil provides superior testing which supports the essential geotechnical investigations. From here we can utilise our multi-disciplinary team who provide structural, civil and natural resource engineering support alongside our surveyors and architectural draughters in delivering a successful outcome for each of our clients.

We are a community focussed company, and love being involved in our local communities visions for the future. We have provided our services to the Camera Obscura project in Whangarei and and ramping up to help out with the new Hundertwasser Art Centre building. See more about our community involvement in our blog here.

Cook Costello is a member of ACENZ and the NZ Green Building Council.
