Professor Ian James Warrington CNZM is a Palmerston North horticultural scientist and science administrator. He was former chief executive of HortResearch (now Plant & Food Research). He was a senior administrator at Massey University until his position was axed in a cost-saving move. He received the T. K. Sidey Medal in 1984, an award set up by the Royal Society of New Zealand for outstanding scientific research. He was appointed a Companion of the New Zealand Order of Merit (CNZM) in the 2011 New Year Honours.
