  • 1990

    Our Humble Beginnings

    When Rayner Consultants started in 1990 we inherited two desks, one drawing board, a set of plan drawers and purchased one computer - the very latest 286 AT!

  • March 1995

    Our First Milestone

    We passed our first milestone in 1995 when we opened an office in Auckland in conjunction with Chow Hill Architects to provide our Auckland clients with a local service and act as a base for expansion in the Auckland area.

  • October 1997

    Gaining Fame

    This came in 1997 when Jonah Lomu assisted the Prime Minister, Jim Bolger to open the Manukau Superclinic for South Auckland Health. As an integral part of the design team we were reponsible for the design of all the building services from the lifts to the lighting and from piped medical gases to the complete air conditioning system.

  • April 2015

    The Present Day

    We have survived several ups and downs of the economic cycle since then through which we have learned a lot. As always our clients' priorities come first as we seek to provide them with quality designs which meet all their needs and are fit for purpose.

Senior Mechanical Engineer

We are responsive to our clients' needs and flexible to make changes to our designs to suit their wishes. We identify potential problems early on in the process and our innovative approach finds solutions which others don't think of. The specifications we write are concise and clear so that contractors know exactly what they are expected to do and our reports are logically written in a way that makes it easy for our clients to understand them. Above all we communicate with our clients regularly so that we understand and meet their expectations..
