We provide professional engineering services in the fields of geotechnical engineering, water resources, and pavements.

2013 to Present:  GeoSolve Engineering Consultants

The former Otago staff of Tonkin & Taylor Ltd formed GeoSolve to meet the particular needs of the Otago and Southland market. For our clients there was no reduction in the range of professional services provided or in the staff providing the services. We have now grown to over 50 staff based out of offices in Dunedin, Cromwell, Queenstown and Wanaka. Pavement testing is undertaken across New Zealand and abroad, with operational staff based out of Cromwell, Wellington, Tauranga and Auckland.

1993 to 2013:  Tonkin & Taylor Ltd Otago Branch

Starting in Christchurch, Graham Salt, now GeoSolve's Technical Director, established the South Island offices of Tonkin & Taylor Ltd, a larger international consultancy. He then went on to establish the Dunedin, Cromwell and Queenstown offices where GeoSolve staff still operate today.

Our mission is to continue assisting Otago and Southland's growth by providing clients with smart engineering solutions with a focus on quality, efficiency and delivery.

We pride ourselves on delivering quality work on time and to budget. We maintain a quality assurance system which is ISO 9001:2008 certified. This quality mark provides independent assurance that our internal processes and systems are compliant with the Standard. Clients can be confident that their projects are well managed and documented with efficient and effective planning, communication and administration. We are also a member of the Association of Consulting Engineers NZ (ACENZ).

Our staff are our greatest asset. For that reason the health and safety of our staff and others in the workplace is paramount to us. We operate a pro-active health and safety policy with comprehensive procedures to ensure the utmost safety in the workplace. We are a registered Level 3 member of SiteWise.

We strive to be at the forefront of the engineering field in order to deliver our clients the very best design solutions. Our focus is to ensure continual learning and development of staff which promotes a creative dynamic culture.
