There's claims continued Houthi strikes in the Red Sea are to blame for high shipping costs in this country. 

Another vessel sank last week after being struck, killing three people in the shipping channel and putting strain on the global supply chain. 

It's caused shipping costs in New Zealand to rise by three times last year's levels. 

Customs Brokers and Freight Forwarders Federation former president Chris Edwards told Mike Hosking that geopolitics play a huge role in international shipping. 

He says that now, shipping vessels need to travel further to avoid the Red Sea which increases costs.
