The LVRs have been highly successful in cooling the housing market, but even the Reserve Bank would acknowledge that they have been just one of several factors. It's possible they are getting too much credit.
The retail banks have also tightened their lending based on concerns that the market was in bubble territory.
Nevertheless LVRs stand out as a piece of policy that is doing what it is supposed to do.
Specifically LVRS were designed to target New Zealand's dangerously high levels of housing debt and remove the wider risk to the economy.
The growth in mortgage lending has slowed but not by enough yet to say that the job is done.
It seems highly unlikely that Reserve Bank Governor Graeme Wheeler or his immediate replacement Grant Spencer will be swayed by lobbying.
Spencer is currently head of financial stability for the Reserve Bank so was instrumental in putting the LVRs in place.
Real Estate agents are unhappy because the market is seeing a huge slump in the volume of sales - that effects their livelihood.
Their industry concern is understandable
But the slump in the past few months is largely to do with the toughening of restrictions on investors - the big change to LVR rules last year.
REINZ's claim that LVRs are hitting first home buyers is disputed by Kiwibank chief economist Zoe Wallis.
"While REINZ notes that LVR restrictions have been particularly hard on first home buyers, the data suggests that the recent changes to property investor lending LVR restrictions have instead opened up some opportunities for first home buyers and other owner-occupiers," she wrote last week.
"The latest round of LVR changes has meant that the percentage of bank mortgage lending to investors has fallen from 33 per cent of all loans in July last year, down to 24 per cent.
"Over the same time period the share of lending to first home buyers has increased from 11 per cent to 14 per cent.
"Lending to other owner occupiers (i.e. people moving up the property ladder) has also increased," she concludes.
Many first home buyers won't need a 20 per cent deposit either. LVR rules allow banks to offer 10 per cent of their loans to owner-occupier buyers who have less than 20 per cent deposit.
So basically if you have a decent job and in excess of 10 per cent on a good solid property then there is a good chance you can find a bank that will lend to you.
And even if that takes more time, LVRs are helping your cause.
You are less likely to need a $200,000 deposit if we stick to our guns now.
Prices are falling, so the pressure to get in the market quickly has gone. Would be home owners can keep saving without feeling like they are being left behind.
There will of course be some, ready to buy now, who feel hard done by.
But it seems that the most aggrieved parties right now are would be investors and the real estate agents themselves.
Giving up on LVRs now would be akin to quitting a tough fitness regime after you've done most of the hard work but before you reached your goal.
It would be a wasted opportunity.
