New Zealand's largest supply chain collaboration has signed another deal with an international shipping giant. 

Kotahi has entered a second decade partnership with Maersk, which will allow for $160 billion worth of cargo to be exported on a reliable supply chain. 

Kotahi chief executive David Ross told Mike Hosking that it offers needed certainty to some of New Zealand's largest exporters. 

He says it's an exciting agreement which gives 10 years of international shipping reliability.
