Partner Organisations


Since 2002, we've provided consulting services at the senior level to the public sector, private businesses and NGO's in New Zealand, and internationally.

We appreciate that you ask for our assistance because you are under pressure or may need specialist expertise that it doesn’t make sense to retain on your team.  Therefore delivering to your expectations with regard to time, cost and quality is integral to the success of our business.

Our clients tell us that they appreciate the tailored approach we take to each assignment, how easy we are to work with and the high level of professionalism they can count on from our people

Our leadership team is a tight group of Partners and Senior Consultants. Together, they bring substantial senior expertise – a valuable combination of public and private sector management experience coupled with many years consulting. We are very engaged in the challenges our clients are grappling with.

Our wider team includes Associates and Consultants most of whom have at least 10 years’ experience in their field of expertise. Our team of analysts are employed for their intellectual ability and work ethic and work closely with the rest of the team.
