In Auckland, that number moved from 66 per cent to 68 per cent. The share of renters remained unchanged at 30 per cent.
Affordability for renting households nationally improved by 2.8 per cent between June 2015 and March 2016.
Cabinet asked for an official measure to be created in 2012.
The ministry said it gave a more accurate picture of how much New Zealanders spend on housing and tracks whether housing is becoming more or less affordable over time for renters and aspiring first home buyers.
The latest measure also included a Housing Percentage perspective and a Housing Index perspective.
"By providing these two additional perspectives MBIE can outline a more comprehensive view than the original benchmark as a standalone series," MBIE general manager of evidence, monitoring and governance Michael Bird said.
"As we develop the measure into a Tier 1 Statistic we will continue to trial further refinements to ensure it is fit for purpose, in a collaborative process with Statistic New Zealand."
MBIE said it is confident about bringing the Housing Affordability Measure data closer to real time in future.
