She has worked in real estate in Whangarei Heads for nine years and said houses usually sell in summer. "But I've been selling all through the winter."
Tony Collins, Chamber of Commerce Northland executive, agreed that the growth in the area would result in a need for more storage. "This is a key piece of infrastructure. You can see with the amount of traffic ... there has been growth out there."
One use for the storage units, he believed, would be for those who had moved to the Heads and required units.
He said the recent refurbishment and rebranding of Flames Hotel could be seen as another sign of change in the suburb.
The development was being completed by Guyco Construction and under Rosemorn Industries, both headed by Greg Guy, who owns the Strand and Civic arcades.
Mr Guy declined to comment on the project.
The 0.74 ha site was on Business 3 Environment zoning, and planners said the development would "support the existing service function of the existing Onerahi Shopping Centre".
Business 3 Environment zones include shopping centres outside the CBD and business areas near residential zones.
According to WDC rates records, the site had a capital value of $5 million and a land value of $4.85 million.
The consent document outlined that the centre could open from 7am to 7pm for clients to access units, with the fence only being live while the facility was closed.
Onerahi Community Association chairman Nick Connop said he was pleased with the development and it was a good use of the space.
He said Onerahi still needed further development, such as the addition of a cafe or restaurant, a drop-in youth centre and a second-hand store.
