What would be a good solution would be to build rectangular or square houses and build them on floats.

They could be sitting on a gravel bed, be on floats and have mooring posts which the houses could be attached to. They would need to have flexible pipes for the services, but that could easily be allowed for.

That way if there is flooding, the house just floats up a bit. Could have a dinghy as well to get around if the water is too deep.

Houses in my area have to be built a minimum height above ground level, after a flood in 2015 damaged over 1000 places. We have new building going on next door, and the section has been raised by around 500mm.

Waterworld, here we come.

Do you really want the Councils to implement even more building standards? Where would it stop? Certified mooring anchors, flotation ratings for houses with roofing and cladding materials of differing weights, standards for streamlining of house shape and orientation in regards to expected flow rates...?

Build your house on a hill if you're concerned about flood risk. Simple fix.

In the Edcumbe floods it was found majority of properties that suffered flood damage were on flat concrete plinth . Its cheap &easy to build which makes it popular .Personally ive never lived in one always prefered it to be at least 3-400 mm off the ground .Insurance companies are looking at higher premiums for houses built on flat plinth

Concrete plinth floors also fare far worse in earthquakes I would imagine, with what damage that does occur being far more problematic to repair.

The Queenslander style seems to work for them in most of QLD Australia
maybe that style should be implemented here

We know where sea level rise will endanger property. So why are councils not proactive on that basis?

Well if the house was on floats, it wouldn't matter.

A great deal of Christchurch will be underwater in a few decades due to noone caring out outrageous pollution.

And Devonport, where the naval base is, will be an island.

similarly Mt Maunganui peak. The ismuth that makes up the residental areas of Mt Maunganui and Papamoa is less the 10m above sea level, with much of it being much less, so rising sea level or tsunami activity from White Island or Mayor Island will/would potentially wash the area clean.

Most of the world's biggest cities are coastal, and yet apart from a couple of really forward thinking planners no one is really talking about that. Or better moving them somewhere higher, while they have time to do it...
