Blair Houlihan

Managing Director

Blair has significant experience as a senior procurement and business optimisation consultant across a variety of industries. He has a strong understanding of what is required to get things done, having started two successful businesses and with hands-on experience in senior operational roles that are all about delivery performance.

Having a strong background in procurement and project delivery, Blair is acutely aware of the importance of getting quality design and engineering support from the earliest outset of a project.

As a strong advocate for growing local capacity through the development of Northland business, Blair and his team have made significant contributions to the design and implementation of local and Māori business development initiatives that have received international recognition. In the delivery of these initiatives, it has become increasingly apparent that Northland and in particular the Far North has a significant shortfall of professional engineering design capability. A local solution to a local problem is the ultimate goal, hence Blair’s commitment to Trine Kel.

Kevin Hoskin

Director

Kevin is an experienced civil project manager, providing support to clients including Waka Kotahi, FNDC and WDC. His core skills range from managing a delivery team as Principal on large scale construction projects, to asset management, project scoping and pricing works. With a background in contract management on civil construction and maintenance contracts, Kevin talks the contractor’s language and builds effective relationships to get the best result for the project.
 
What sets Kevin apart is his management style; he identifies potential issues a project may face and directly manages them early to avoid impact on project delivery. His even temperament allows him to communicate effectively with all stakeholders and diffuse situations that may otherwise escalate. Kevin’s exceptional and inclusive people management skills ensure he has a cohesive team working towards the same outcomes.
 
Kevin knows that growing high quality engineering capability in Northland is important to the region’s growth and looks for opportunities for innovation and mentoring; he is particularly passionate about getting young people into the industry and providing training to set them up for a successful career.
