I dont buy the equity issue. The bank loaned the funds, its their problem. If houses dropped 20% today, the owners are still paying the mortgage. The bank has a risk, and the owner lost equity. Should interest rates go up a lot, thats another issue, as that will affect the affordability of the repayments. As you say, it would not surprise me if they didn't do anything, and prices stay static.
If a bank in NZ fails, it becomes everyone's problem, and it means a potential run on the other banks, as we don't have any government guarantee scheme like other countries. Also it may mean that a bank may need to be bailed out by the tax payers. Although they say a bank failure is an 'unlikely event', it has happened before.
The problem is that banks never want to be lending more to someone, than the house is actually worth. If they are then it causes all sorts of problems for them. That is why no one wants the price to plunge, except first home buyers, who have been locked out of buying in some place. So if houses do say static for 10 years, in reality they are dropping in price due to inflation. Inflation is probably going to save NZ from this housing crisis in the long run.
Bank failures are very rare, no bank fails and there is a cash run, thats a many decades ago, and more a US type of thing. BNZ had issues yonks ago, it was bailed out. And I imagine that more an underwriting thing than giving then gazillions. Sure, banks want security, but they also loaned on houses in a heavily rising market, so they are as guilty as those that bought in a heavily rising market, if the bubble collapses. If it did, they have risk, but the mortgages are still being paid, and an underwriting could occur. But not apply to owners who chose to sell.
