What We Do

Thornley and Associates provide an extensive range of surveying services to support and facilitate your land development project. Working throughout Greater Auckland on large and small land projects, we provide surveying, subdivision consultancy, land development planning and civil engineering services at a reasonable cost.



Our skilled team of professional, licensed cadastral surveyors will deliver accurate survey information to a high standard using the latest processes and technology.

In the town planning, construction and property development sectors, the role of the land surveyor is crucial. We are responsible for accurately determining section boundaries which then determine the positioning of everything on the surveyed lot including roads, drainage and buildings. That’s why you want an Auckland surveyor you can rely on.

Bringing over 50 years of experience, and the latest in surveying technology, Thornley and Associates lead the way in the field of land and property development surveying.

We offer a full range of surveying services including:


From small single section subdivisions to large residential, commercial or multi-storey high-rise land developments we cover any type of subdivision in Auckland including:

  • Infill urban subdivisions.
  • Large urban developments – residential and commercial.
  • Rural subdivisions.
  • Freehold subdivisions, Unit Titles, Cross lease & Cross lease conversion.
  • Roading, stormwater and wastewater design and plans.

Subdividing land can be a complex and expensive process. The need for a Resource Consent is almost guaranteed, planning provisions and procedures differ from one area to the another. The team at Thornley and Associates will use their extensive knowledge and experience to guide you through the subdivision process from start to finish.

At Thornley and Associates, our surveying team works closely with our team of civil engineers to ensure accuracy and adherence to all necessary Auckland Council land development regulations and procedures.

When undertaking a land development, we will first survey the site to map out what exists and ensure all site constraints and possibilities are understood. Our civil engineering team is then able to provide land development engineering solutions that are cost effective, safe and environmentally friendly.
