Based in Invercargill for over 40 years, Bonisch has a proud history of providing land development services to the Southland and Otago Provinces and, more recently, throughout New Zealand.

Founding director and registered surveyor Noel Bonisch initially registered the company as Noel Bonisch Limited in 1973. As the staff roll grew, the company became known as Bonisch Surveyors.

The company has been involved in many high profile projects throughout the Southland and Otago regions – from the Tiwai Point aluminium smelter and Fonterra developments at Edendale to rural subdivisions in the Gibbston Valley and large-scale residential developments in Te Anau, Winton and Invercargill.

Changes in land use saw the industry become increasingly multi-disciplinary and, in recognition of this, the company offering was broadened to include a whole range of professional land development consulting services. As staff numbers grew to double figures a branch office was opened in Te Anau where Bonisch continues to be active in the local community.

In 2010, long time employees Boyd Wilson and Craig Ireland took over the reins on Noel's retirement and registered Bonisch Consultants Limited. Boyd and Craig were later Joined by Glenn O'Connor.

Under their leadership, Bonisch has continued to grow. The company's Head Office remains in Invercargill, with branches in Te Anau, Christchurch and Kaikoura.

A "can-do" attitude and a commitment to personal service has seen Bonisch build a strong relationship with a number of national clients, and today the company works on a diverse range of projects throughout New Zealand.
