He was a founding director of Rotorua-based APR Consultants, set up in 1983, offering a range of services in planning, analysis and research.
Upon stepping down, Shaw said the values of a public health system had always been very dear to him and acted as the key driver for his work on the board.
"No matter where people start in life we need to ensure that they can access the best public health and education systems available."
He said the Lakes DHB was unique, with the size of the hospitals making them attractive for staff and patients.
He said iwi partnerships were fundamental and the DHB was not doing as well as it needed to in terms of Māori Health.
However he added that the new health strategy rolled out this year, Te Manawa Rahi represented a strengthening of the DHB's long-held commitment to health equity.
Also stepping down were ministerial appointees Ana Morrison, Warren Webber and Stuart Burns.
The three new appointees are Sir Michael Cullen (former Deputy Prime Minister, Minister of Finance, Minister of Tertiary Education and Attorney-General), Lana Ngawhika (Te Arawa, Tūhoe) who served the former Te Arawa Māori Trust Board on the treaty settlement that saw the return of 14 Rotorua lakes to Te Awara ownership and psychiatrist and Māori health leader Rees Tapsell (Te Arawa).
The new board will meet in December.
