Banks will be able to lend 5 per cent of their new loans to investors with a deposit of less than 30 per cent (down from 35 per cent).
Mark Collins, chief executive of Mike Pero Mortgages, welcomed the easing and said it would help first-home buyers but predicted it would not see banks throw open the doors to lending.
"Just because they have eased the door open does not mean banks will open their doors again. It will depend on their credit and risk appetite."
Collins said banks were under a lot of pressure around responsible lending which meant they had to behave appropriately.
That meant any lending over the 80 per cent loan to value ratio was stress-tested pretty hard, he said.
Stress-testing is where banks test a person's ability to pay a mortgage on a higher interest rate than the advertised rate - typically around 7 or 8 per cent.
Collins said even a 10 per cent deposit on a house in Auckland required a lot of saving as banks did not accept deposit gifts for higher-risk lending.
And he warned homebuyers to be wary of low equity fees and charges that came with having a small deposit.
"While it's a great move. It is probably not going to make as big a difference as it might sound."
In terms of the change for investors, Collins described it as a "rounding error" designed to help banks keep inside the restrictions.
He said the LVR restrictions combined with a tightening of the bright line test and tenancy changes had seen investors drop out of the market.
Kelvin Davidson, a senior research analyst at property data firm CoreLogic said the change may provide a kick-start to sale volumes provided more borrowers could secure loans, but it was not a guaranteed outcome.
"Despite the Reserve Bank's loosening of LVR limits, an increase in lending is not a clear-cut outcome.
"After all, lenders may choose to continue on their cautious path, especially since today's Financial Stability Report also highlighted the RBNZ's view that 'higher capital requirements are necessary, so that the banking system can be sufficiently resilient whilst remaining efficient'.
Davidson said a requirement in future for the banks to hold higher capital buffers would tend to dampen lending flows.
Antonia Watson, ANZ's Managing Director Retail and Business Banking, said the bank wants to make sure customers can comfortably repay what they borrow.
"In practical terms we don't think much will change. What's had most impact recently was moving the bright line test from two to five years. That's driven a lot of capital gains speculators out of the market which has dampened house price inflation in places like Auckland.
"There is still growth in house prices because there's more demand than supply, but it's not as rampant as before which hopefully has made it a bit easier for first home buyers in the market. While we can't talk exact numbers, we will have the ability to write more owner-occupier home loans above 80 per cent under the new regulations.
"As always, we take our commitments to responsible lending seriously. While we will have the latitude to write more home loans over 80 per cent LVR, we want to make sure our customers can comfortably repay what they borrow," Watson said.
Reserve Bank governor Adrian Orr said risks to New Zealand's financial system had eased over the past six months but vulnerabilities remained.
"In particular, households remain exposed to financial shocks due to their large mortgage debt burden."
But he said both mortgage credit growth and house price inflation had eased to more sustainable rates reducing the riskiness of new house lending.
"In response, we are easing our loan-to-value ratio (LVR) restrictions on banks' new mortgage loans."
Orr said if banks' lending standards were maintained he expected to further ease LVR [loan to value] restrictions over the next few years.
But Collins said even if the restrictions were lifted the banks may continue to remain cautious.
Bindi Norwell, chief executive of the Real Estate Institute of New Zealand, had hoped the Reserve Bank would drop the minimum deposit level for owner-occupiers from 20 per cent to 15 per cent across the board.
But she said she was not surprised that it had chosen not to do this as New Zealand's two-tier market would be causing the Reserve Bank some concern.
"With house prices stabilising in Auckland for 19 months now, REINZ has been advocating for an easing of LVRs for first-time buyers.
"However, with house prices continuing to rise and reaching record median prices in a number of regions we're not surprised that the Reserve Bank has chosen to leave LVRs for owner occupiers as they are for now."
But she said the easing should mean there was a chance for more first time buyers to have access to lending that they haven't previously had.
"We continually hear feedback from real estate agents around the country that with median prices rising to record levels in the regions that first time buyers are just finding it too difficult save that deposit to purchase their first home and to get into the property market.
"Any window of opportunity for young couples to get a foot on the property market is to be welcomed."
Andrew King, chief executive of the New Zealand Property Investors Federation, said the easing for investors was positive.
"It is certainly in the right direction." But it was probaly not going to be enough to overcome a lot of the other changes that were putting cost pressures on investors.
King said he would like to see deposits for investors fall to 20 per cent relatively quickly as that was the historical level banks had lent at.
He said investors and landlords were facing challenges on a number of fronts and were particularly concerned about proposals by the Inland Revenue to ring-fenced tax losses for property investors and changes to the Residential Tenancies Act.
The Reserve Bank introduced high loan to value restrictions in October 2013 to cool the property market.
They were meant to be a temporary measure and have been tweaked on a number of occasions since their start.

At the start of this year, the restrictions were changed to allow banks to lend up to 15 per cent of new loans to owner-occupiers to those with a deposit of less than 20 per cent.
While up to 5 per cent of lending to investors is allowable to those with a deposit of less than 35 per cent
The changes have seen first home purchases grow percentage wise while investor purchases have dropped.
Banks face losing their license to operate if they don't stick to the restrictions - a consequence which has meant most lend well under the restrictions.
