Corporal Douglas Grant approached life the way he wrote he rode his motorcycle - "above the speed limit", his commanding officer told his funeral service in the Linton Camp gymnasium near Palmerston North.
Lieutenant Colonel Chris Parsons said he had been a "free spirit" who went the extra mile.
They had joined the SAS together in 1996.
Corporal Grant's grieving wife Tina said he took care of everything he touched.
He was a storyteller and told stories like no other, she said. He wrote stories as well and since his death she had gone through some of his stories.
