It is the second time in three years that the limits for the grants have been raised.
Labour leader Andrew Little said the latest changes showed the key problem in the housing market was affordability, not finance.
"It's tinkering at the edges," he said. "Especially if you see that up until now, only 9 per cent of the applications under the scheme have gone to Auckland, where you've got roughly a third of the population."
In the year to March, 1139 out of 11,943 grants were paid to first-home buyers in Auckland. That is well short of Smith's prediction in 2013 that 3000 grants would be given out in Auckland a year.
From August 1, income caps for the HomeStart grants will rise from $80,000 to $85,000 for a single person and from $120,000 to $130,000 for a couple.
Homebuyers earning less than the income threshold will qualify for the subsidy if they buy an existing house worth up to $600,000 in Auckland - up from $550,000.
The Herald found there were 1342 property listings in the broader Auckland region with an asking price of less than $600,000 on Trade Me yesterday - around a quarter of the total listings for the region.
The majority of the listed properties were going to auction, meaning they could be pushed above the $600,000 threshold.
A large number were central city apartments, and some were leasehold properties. Most were being sold in Manukau, Manurewa, Papakura or Franklin.
They included a three-bedroom house in Clendon Park, Manukau, which was advertised as "perfect for a first-home buyer or a hungry investor", and had an asking price of $570,000.
While Little was critical of the impact of the HomeStart grants, he did not go as far as saying Labour would scrap them if in power.
