The partnership also provided the opportunity for local surgeons to learn from world-leading experts.
Urologist, Associate Professor Peter Gilling said Mr Blyth was a world authority in paediatric surgery.
"It's great to have him operating in Tauranga Hospital, where not only do our children with complex surgical needs benefit, but Bay of Plenty doctors are able to observe and learn."
During his visit, Mr Blyth completed hypospadias repairs on children, a congenital condition that occurs in one in 150 births. He was assisted by paediatric urologist Mr Liam Wilson.
In America Mr Blyth completed the hypospadias repair on a daily basis, but in New Zealand, the surgery was less frequent.
Mr Blyth left New Zealand in 1985 and is now based in Denver, Colorado. He is originally from Motueka in the Tasman region of New Zealand.
