Our History

DStevens had its humble beginnings in the Christchurch suburb of Cashmere. Founded in 1955 by the late Derek Stevens, the company built many buildings regarded as a benchmark of quality construction. Derek worked hard to establish the company in a competitive Christchurch industry undertaking major construction projects that included high-end housing and commercial work by expanding his team to 12 skilled carpenters.

Derek and his family relocated to Gisborne in 1966 and set about establishing DStevens as a premier construction and joinery company. One of the first projects DStevens landed was the high-profile development of Kaiti Mall. In 1970, DStevens saw an opportunity to expand their services to include Rylock aluminium windows and doors. The service has since grown to become an integral part of the construction company.

From our humble beginnings, we have grown to provide our clients with a truly integrated building service, including construction, joinery and interiors.

Sustainability is no longer about simply minimising impact on our surroundings. Today, it’s also about wellbeing and biodiversity for individuals, communities and the environment. For us sustainability isn’t an ‘add-on’ service, it’s an overarching priority, a lens through which to focus our solution-based thinking – building the best for you and the planet.

Fundamental to all our work is a commitment to social and environmental sustainability. Because of that, our projects involve extensive collaboration with clients, users, and other stakeholders. We know that with a well-conceived and well-delivered project we can help things run more fluidly, improve people's well-being, and make life more enjoyable.

Sustainability is a core value of our company. We believe sustainability is integral to the achievement of construction excellence. We work with our clients to identify the environmental potential and set goals to reduce the construction impact of each project; we then seek out practical means by which to deliver these goals.

Recognising the wide range of environments that the building industry impacts, DStevens remains committed to careful planning and execution of each phase of a project. We’ve implemented sustainable construction methods in commercial buildings, residential projects and civic and education facilities.

We believe green buildings have the potential to be enablers of a holistic prosperity never seen before, helping cities, communities and the environment to flourish, and the individuals within them to thrive.


DStevens is committed to maintaining a safe and healthy workplace to ensure that our employees and others are not injured. Our goal is to eliminate all accidents and incidents.

To achieve this goal we make safety a priority on all sites and jobs and we require active participation by everyone in our business to adequately plan the work we are carrying out and to act safely at all times.

We believe that an empowered culture of health and safety amongst our people, subcontractors, clients and wider project team, is what drives success. We are proud to hold SiteWise Gold accreditation by Site Safe New Zealand, certifying our health and safety capabilities, processes, and our strong commitment to creating a culture of safety in the workplace is among the very best in New Zealand.

It is our policy to take all practicable steps to comply with the provisions of the Health and Safety at Work Act 2015 and the Health & Safety at Work (General Risk and Workplace Management) Regulations 2016, and all other codes of practice and guidelines applying to our business.


DStevens is partnered with industry-leading and trusted companies to deliver quality built environments where you can live, work, learn and do business.

Since 1960, DStevens has been a member of the New Zealand Registered Master Builders Association. Our Managing Director Peter Stevens is a long-standing member of the Gisborne Master Builders Executive – contributing his knowledge and expertise to improve building standards in our region.

We are proudly associated with Master Joiners – a group of ten regional associations throughout New Zealand that represent the best in craft, manufacturing and business development.

DStevens was an early adopter of the Licensed Building Practitioners scheme, launched in 2007. The scheme is designed to encourage competent building practitioners to build it right the first time – a practice we firmly believe in.

The memberships we hold with Site Safe New Zealand and ThinkSafe give our team access to the latest Health and Safety documentation and processes. Our own Health and Safety framework is independently audited and accredited by SiteWise.
