The victim was found severely beaten, bloodied and slumped outside the clock tower public toilets by two females friends he had been celebrating a birthday with during the night.
Walsh and Broderick had been drinking at Turks Bar in Havelock North earlier in the night and immediately following the assault Walsh bragged about punching the victim in the head up to seven times to friends at the Havelock North McDonald's.
The victims family told Hawke's Bay Today outside court their brother's vision and speech had since returned, after he spent five days in Hawke's Bay Hospital following the assault.
"He hasn't gone back to work yet ... he has a lot of issues he's dealing with," said the victims sister.
The 32-year-old man has suffered from several ongoing issues including headaches, fatigue, balance and co-ordination issues and neck and upper chest pain.
Walsh was convicted and remanded on bail until October 22 when Judge Tony Adeane asked for Walsh to go through the restorative justice process.
Broderick, who has pleaded not guilty, was remanded on bail until a case review hearing on November 10.
