Properties purchased as recently as 2011 are selling for hundreds of thousands of dollars above their valuations.
A rundown four-bedroom villa in the central city suburb of Grey Lynn fetched $1,445,000 last week, 50 per cent above its valuation of $980,000.
It is also understood a streamlined process for consent applications for housing developments will be considered by an independent panel of at least three people appointed by the council. Members could include independent planning commissioners, Local Board chairs and community representatives.
The streamlined process will apply to applications in "brownfield" sites within the existing urban boundary - such as Hobsonville Point and Tamaki - and "greenfield" sites the council has earmarked for 160,000 new homes over 30 years. The rural areas includes the towns of Pukekohe and Warkworth and communities served by the Northwestern Motorway, such as Kumeu and Brigham Creek.
Applications will have to meet certain criteria, including numbers of dwellings and access to infrastructure.
It currently takes an average of three years to get consent for new housing developments. An announcement on the time it will take under the streamline process will be made this afternoon.
The deal will give effect to some parts of the council's new planning rulebook - or unitary plan - which the council wanted to have legal effect from September and the government insisted go through a three-year process to ensure Aucklanders were involved.
Declining home affordability have emerged as a major economic and political headache.
