"The departure of David Jones from Lambton Quay is going to have a huge impact on the retail strip down in that part of town."
Harford said a significant player in the retail market needs to take over the building.
"It's really important we have a strong retail offering in that David Jones space and indeed around it."
He said declining numbers of people entering the city could make it difficult to attract a business to take over the site.
"One of the problems we have seen in central Wellington is that foot traffic is down – it's been down since Covid but it has been declining for a very long time."
Wellington Mayor Andy Foster said the David Jones building was a key location on Lambton Quay.
"It's an anchor site for the Golden Mile so having a good drawcard in the building is really, really important."
Foster said he hoped a new business could utilise the space better than David Jones has.
"David Jones, while it will be sad to see them go, it never quite met the Wellington market in the way Kirks did over many, many years ... so we hope future businesses will be able to do so"
Foster has been having conversations with the owner of the building, Robert Jones Holdings Ltd, since it was announced David Jones would be shutting down.
However, Foster told the Herald he would not go into the details of those conversations.
Wellington Chamber of Commerce chief executive Simon Arcus said the closure of David Jones without the announcement of a new tenant is another question mark over Lambton Quay and the city.
"It tells us a bit about the current operating environment for business, accentuated by the impacts of the Omicron outbreak and the current red traffic light restrictions."
Arcus said it's a particularly difficult time for hospitality and retail businesses.
"We've still got people staying home and working remotely because we're at red - while the reality is that we can be back in the city safely.
"Wellington will be back, but we need the confidence to get people back."
A David Jones spokesperson said they remain committed to New Zealand through their Auckland store and their David Jones online store coming in the second half of 2022.
