He moved to Hawke's Bay from Auckland a wealthy man in 2006 after selling payroll company Comacc to MYOB and, with no wine industry experience, bought Salvare Estate at Bridge Pa with wife Bev "because I soon got bored".

GPS locates employee/s' location and can take a photograph at login for extra data integrity.
"While we could have developed TimeHub offshore I wanted to keep it New Zealand made, so we have developed the system in Hawke's Bay through a partnership with a local development company WeaveIT, whose team include current and former students from EIT's School of Computing.
"This gives us the best of both worlds in that we get knowledge capital and experience paired with youthful enthusiasm and creativity. The student aspect was important to me as I wanted to give some students a chance to work on something real, which they could see go to market."
The plan, when launching TimeHub two weeks ago, was to keep clients local.
"I wanted the first one to be in Hawke's Bay and small, so I can manage it a bit better, but the first one happened to have 50 employees in Motueka, of all places."
The South Island business found out about TimeHub through one of several payroll companies TimeHub partners with.
"We are the front end of making the payroll better - if you capture your data better then payroll works better."
