Alex McLellan died as a result of injuries suffered in a workplace accident at McLellan Freight, the company he founded.
In a Facebook post the New Zealand Heavy Haulage Association paid tribute to Mr McLellan, a "loyal member" for more than 28 years.
"It is a sad loss to all those members that knew him, but especially to his family – and we pass on our sincere condolences to the family at this very difficult time.
"RIP Alex you were a true achiever in whatever you did, and you will be sadly missed."
Mr McLellan was last year presented with a Chairman's Award to recognise his achievements and contribution to the association.
A police spokesperson said emergency services were notified about 5pm yesterday that one person had been seriously injured at McLellan Freight in Barr St.
"Sadly, the person died as a result of their injuries," the police spokesperson said.
"Inquiries are ongoing and WorkSafe has been notified."
