About Us

Onus Construction Management Limited is a Nelson based, client focused, efficient Project Management and Construction Management Company.

We are independent of consultants and contractors which allows us to take impartial views of projects thereby able to offer clients best advice on their project requirements.

After identifying the need in the construction industry for a totally client focused company, that delivers on what it says it will do, Onus Construction Management Limited was established in September 2012.

We pride ourselves on delivering our service to levels beyond what is required in a contract. Solving problems is what we do whether it is part of the contract or not.

We recognise that having being given the privileged position and responsibility for the client’s funds and other project interests is a significant act of trust from the client. Our actions in delivering your projects are directed at ensuring the faith and confidence shown in us, is reciprocated.

The construction industry is diverse, complex and full of hazards. We utilise our skills, knowledge, experience and ethics to facilitate positive outcomes for clients on capital works projects.

What We Do

Construction Management

In this form of delivery there is no Main Contractor and all trades are let and managed through a project / construction manager. The benefits here include complete client control of their site and project. Reduces margin on margin scenarios that are common in the construction industry.

Project Management

Onus Construction Management Limited recognise that not all projects are the same and clients have different requirements. We will tailor our services and form of engagement to suit your specific requirements.
