It's just made its largest investment in its 40-year life in a plant in Porkenaw, south of Auckland.

Adam Jackson is the general manager.

Some of it comes from Asia and some from the US.

So for you, it's a mixture of places.

I was at Plumbing World yesterday.

They're telling their customers that they're going to be putting up prices of plumbing products by 30% come 1st of May.

Are you in the same boat?

You're putting your prices up by 30% as a supplier to the plumbing outlets now.

Just to be clear, you're not putting up your prices by 30% from the 1st of May?

Is there any danger or risk that you might have to, you know, close your plant or lay off workers?

And when you talk about some of those big projects where you are supplying your customers, what are they?

Auckland University Professor Brent Young teaches chemical and materials engineering.

He's working with some of our largest companies, including Becker, NZ Steel and Fonterra, on projects that don't use fossil fuels.

He says petroleum-based products are everywhere, but he's optimistic, even excited, about what's ahead.

I looked at a list the other day.

I was a bit kind of blown away.

Is it really in chocolate?

Hard to believe, isn't it?
