In 2006, Thorne Dallas & Partners merged with Webb Ross Johnson to form what was then Northland's largest legal practice, Webb Ross, with Dallas, McGregor and Perkinson joining the new firm as consultants. In October 2012, Webb Ross merged with Urlich McNab Kilpatrick, creating mega-firm WRMK - a combined workforce of 54, made up of eight partners, 10 lawyers and three consultants, along with legal executives and support staff.
"I've always enjoyed my work," Dallas says, and he is now equally enjoying the pace of being a consultant working four days a week. He has no plans to retire in the foreseeable future.
Bruce McGregor describes his long-time colleague and friend Dallas as "remarkably efficient and effective, and big on detail". McGregor said Dallas liked to keep his private life private, but divulged that he is a car enthusiast who "knows everything about cars" and also has a keen interest in wine.
McGregor said he believed no other lawyer in Northland had practised for a straight run of 50 years.
Apart from changes in legislation, the law itself hasn't changed a great deal in 50 years, Dallas says. He counts the biggest changes as being in the practicalities of legal practice.
Since the 1980s, fax machines and then emails and electronic banking revolutionised the exchange of documents and information.
Dallas was born and bred in Paparoa and was a student at Whangarei Boys' High School, boarding at Carruth House from 1954-58, before heading off to study law in Auckland.
Back in Whangarei, his earlier career saw him handling criminal, matrimonial and family court cases - "I've done everything involved in legal work" - but the naturally reticent fellow was happy to step back from court work as Thorne Dallas & Partners grew.
"It didn't feel right for my personality, the court environment, but I've certainly had a satisfactory career."
