He is semi-retired and acts as a consultant for the firm.
Mr Baker is a past national president of the NZ Society of Farm Management, was a member of the Primary Industry Consultants Registration Board, and is a past member of the Wairarapa and Wellington Land Valuation Tribunal.
He is also a court-sitting Justice of the Peace.
Mr Baker said a role he had taken greatest satisfaction in was being a trustee in the establishment of the New Zealand Rural Trust with Sir Peter Elworthy.
"It was support for farmers, affected by the downturn, about 1986-87."
That trust has now been regionalised, including the East Coast Rural Support Trust, of which he is currently a trustee.
"My whole focus is trying to anticipate needs of farming clients, assist them as best I can."
His JP role was part of "giving back to the community".
