After amassing 148 appearances and scoring 62 tries for Saints, Diggin celebrated his career at the club with a testimonial match at Franklin’s Gardens on Sunday afternoon.
Former Northampton full-back Reihana was one of the men who turned out for the event, which drew a crowd of more than 3,000.
And the Kiwi was full of praise for what Diggin, who is now an Academy coach at the club he joined during his teenage years, managed to achieve during his playing career.
“I grew up playing here with Diggs when he was coming through the Academy and the first time I saw him I knew he was going to be a star,” said Reihana.
“He’s got the character and the strength of anyone and it’s a true testament to him that his career was as large as it was here at the Saints.
“He’s a true Saintsman through and through and full credit to him. I was delighted to come back and help him for his testimonial.”
