A new report estimates 100,000 homes can be built on existing Auckland sites but one expert has questioned that number.
Homes.co.nz cites the potential to subdivide existing Auckland sections to create another 100,000 houses, saying many of the city homeowners could have a potential goldmine in their back yards.
But Bryan Thomson - who today was announced as Harcourts' new managing director in New Zealand from April - questioned that 100,000 figure.
"How many sections can you practically subdivide when you look at sizes, shapes, slopes, location? I'm not disagreeing with the statistics but the question is that just because a piece of land is large enough to be subdivided, is it practical to do so, even if it's allowed under the Unitary Plan?" Thomson asked.
"There are properties where subdivision does make sense but it's not that simple," said Thomson, currently the principal of consultancy Bryan Thomson Associates.
