Each week the NZ Herald and Newstalk ZB's Cooking the Books podcast tackles a different money problem. Today, it's why all investments need a certain amount of safety, and how to organise that. Hosted by Frances Cook.

All but the most blinkered of politicians and property lobbyists admit we have a housing crisis in this country.

Prices are climbing far faster than wages, and as a result some people worry they'll never be able to buy their own home.

One interesting solution to bring prices back down is to increase prefab housing.

Think of it like this. It's always more expensive to create something bespoke, in place, and bring all the workers to that spot to get it done. That's how most of our housing is done right now.

Whereas prefab is exactly what the name says – it's pre-made, elsewhere, usually in a factory.

The workers get into a groove, get most of the parts done in an efficient factory model, and then ship them to the housing site to be assembled.

So why don't we have lots more of this happening?

Well, there's been some red tape that has made this extremely difficult in New Zealand.

As always though, you just need to know the pathways around it.

For the latest Cooking the Books podcast I talked to Scott Fisher from PreFabNZ, and Rupert Gough from Mortgage Lab.

We discussed what's caused problems for prefab so far, which banks are friendliest to it, and what types of law changes are in the works.
