The median house price in Auckland last month was $735,000 - up 20.5 per cent from a year ago.
The new SHAs will offer a mixture of dwelling types with fast-tracked consents at sites across the North Shore, central city, West Auckland and South Auckland.
A proportion of the homes will have to be priced in the "affordable" range.
"And they mark further progress under the partnership between the Government and the council to improve housing supply and affordability in our largest city," Dr Smith said.
The minister and mayor also released the latest Housing Accord monitoring report - covering the nine months from October 2014 to June 2015 - which they said showed building consents in Auckland at a 10-year high.
"This report shows the house build rate in Auckland, at 8300 per year, is the fastest in a decade. The rate has grown at over 20 per cent per year since 2012 - the longest and strongest period of growth ever," Dr Smith said.
However, asked how many homes had actually been built under the accord, a spokeswoman for Dr Smith said neither the Government nor the council kept count of completed houses.
Labour's housing spokesman Phil Twyford said no amount of spin could hide the fact that in nearly two years, only 1019 building consents had been issued in the SHAs.
"Now, the minister won't say publicly how many houses have been completed, he claims that that information's not available."
