Northland based specialists - team players for your project 

Thank you for visiting our website. We currently have very high demand for our services and are focusing on servicing our existing customers and more complex sites. Generally we are unable to complete one off domestic jobs. For more complex sites (such as landslip repair), commercial developments or where a longer lead time is acceptable please still get in touch.


NGS is a husband and wife team providing geotechnical services to the Northland region. As geotechnical specialists we work with your team to deliver trusted results. As Northland locals we know the region and the complex geology we live in.


We offer a full range of geotechnical services from single house sites to large commercial, industrial and land development projects. We can provide a fixed price quote for most projects and will provide you a realistic timeframe.


We will work as a team with your architects, designers, civil and structural engineers and planners. Call us today to discuss how we can deliver for your project.
