Mark Brunton, director of Colliers International, says the current snapshot of the Hamilton central property scene shows a "heap" of vacancies.
"But the outlook is brighter now than it has been over the past three years.
"Major corporates have forsaken the CBD for Te Rapa - it has been a lot easier to erect large office buildings in the suburban areas. They would have been compromised in their footprints in the CBD.
"However, office staff are better served in the CBD as far as shopping and lunching is concerned."
Mr Brunton says retail is looking better in the city centre and he wouldn't expect a further downturn.
"There are some opportunities. Farmers moving to Centre Place could create huge prospects."
Both men see new earthquake regulations and strengthening requirements as a developing issue. They say car parking needs attention but is not the only obstacle for re-populating the CBD. But generally they agree Hamilton's centre is finally moving ahead.
