A global events company is adamant all its suppliers will be paid for their role in the Fifa Women's World Cup

Multiple companies across New Zealand and Australia have told 1 News they're yet to be paid waiting on more than half a million dollars.

Fifa is referring all questions to the company that contracted the suppliers -- CSM Live.

In a statement to Newstalk ZB, CSM says it's taken "longer than hoped" to reach final payment agreements with some suppliers, due to the complex size and nature of the project.

It says it's working to ensure all supplier invoices are settled, and all suppliers will be paid for their work in accordance with their contracts.
