Philip Cox (58) died after a van driven by a Vanuatu fruit-picker crossed the centre line and collided with the car driven by his friend, Arthur Blondell, near Millers Flat on March 7.
The 23-year-old Vanuatu man was sentenced on five charges, including drink-driving, and jailed for three years.
To mark the anniversary of Mr Cox's death, dozens of friends, family and colleagues attended a commemorative service at Mercy Hospital yesterday, which was marked with an unveiling and blessing of a glass and pounamu sculpture.
In addition, it was announced a charitable trust would be named after the the oral and maxillofacial surgeon, and would aim to promote, encourage and support safe enjoyment of the New Zealand outdoors.
The Philip J. Cox Memorial Trust had been developing for some time, and would reflect his philosophy of the outdoors, his widow, Jane Cox, said.
Many people had expressed their interest in supporting such a trust, and any support from those who knew her late husband would be most welcome, she said.
While the full details of the trust were yet to be finalised, it was possible funding would go towards completing an outdoors hut in Otago within five years.
Mrs Cox said she was "proud and honoured" to be a trustee along with Dr Mike Jameson, Arthur Blondell, Tony Guy, and Dr Peter Ashton.
