While Mr Horner said he and his wife had no issue with the living wage campaign, they did not feel the need to become accredited and said all businesses should use it as a starting point for all employees, rather than falling back on the legal minium wage of $15.25 an hour.
"This is how it has to be, there's no question about it," Mr Horner said.
"It's paid dividends for us, we have bloody good staff.
"It's great to know the guys at Ponsonby Rd have done this too."
Mr Horner said he started paying his staff the living wage rate - then $18.80 an hour - in 2014.
"I said long ago we cannot pay people minimum wage, it's the biggest obstacle for progress in New Zealand."
