Murray's exit from the sport ends the pair's eight-year unbeaten streak at 69 races, a period in which they captured six world titles, took gold at the 2012 London Games and romped home in their Olympic title defence in Rio last year.
The 'Kiwi pair' announced after Rio that they would take a year off to weigh their careers before a possible tilt at the 2020 Games in Tokyo.
But Murray, who will turn 35 on Saturday, said in an interview with New Zealand's Woman's Day magazine that his time had come.
"I always said as long as my mind, my body and my heart were in it, then I could do this for as long as I like," he said.
"My mind's been pretty good, my body's been pretty good, but it was my heart that was on the fence. So, it's time to go.
"We made a legacy in the sport and we got to the point where we were always winning, but it was playing on our minds and wearing us down. When we won a race, it was like, job done. We didn't get that elation anymore."
World record holders Bond and Murray also won a world title in the coxed pairs in 2014.
Bond, 31, paid tribute to his rowing partner.
"Eric's retirement from rowing signals the end of an era," he wrote on his Instagram account.
"I am very proud of all that we have achieved as a combination over the last eight years, far exceeding my wildest dreams.
