ACTION
The new Mike Pero Real Estate franchise has opened this week.
"We know the district is increasing in popularity, with many people moving here from further down the country and we know properties are selling well here - why should people have to pay more when they can work with us and save thousands of dollars in commission while still receiving excellent, detailed and personalised service," Ms Martin said.
Ms Struneski said the city had plenty to offer and had "so much potential for people moving here".
"Buying or selling a home can be one of the biggest financial transactions you can make in your life, it needs to be handled professionally and properly, and we don't believe you have to pay higher commission rates to achieve that."
The company has branches at Mangawhai and Kerikeri.
Chief executive Mike Pero said the timing was perfect to open an office in Whangarei.
"Our next-generation culture and philosophies have hit a note with New Zealanders, and we're growing ahead of our expectations."
Mr Pero said the business model focused on offering a lower commission structure "by reducing middle management and utilising new marketing technology", such as online. The official opening of the office was planned for November.
