Ms Johnstone says they hope a cafe will occupy one of the two vacant spaces.
The developers are in discussions with the district council on how best to develop the street front of the site to fit in with the Hihiaua Precinct Plan which sets out a long-term vision for the 16ha of central Whangarei land in the area.
The Hihiaua Plan encourages complementary mixed-use activities including residential, boutique retail, cafes, limited office, community services, entertainment and tourism.
It is bounded by the Hatea River, Waiarohia Stream and Reyburn St and includes the Hihiaua Peninsula, Lower Dent St, Reyburn House Lane, Herekino St and Finlayson St.
The plan, adopted by the district council in 2015, allows harbourside residential development up to four storeys high and "complementary mixed use activities".
It will be progressively implemented through partnership between public and private sectors, community groups, business owners and landowners during the next 20 to 30 years.
