New Zealand Football have confirmed the All Whites will contest a four-nation tournament in Saudi Arabia next month.

At the OSN Cup tournament the All Whites will face hosts Saudi Arabia in Riyadh on September 5 followed by an appearance in the final or third-place playoff four days later. The two other teams are the United Arab Emirates and Trinidad and Tobago.

New Zealand have been mooted as participants in the tournament for several months in overseas media reports although confirmation from NZF only came on Tuesday, just nine days before the first match.

All Whites coach Ricki Herbert will use the games as preparation for the World Cup home and away playoff in November against opponents from the Concacaf confederation.

"It is a real priority for us to work on the systems that we feel can give us the best possible chance in November and that will influence how we play in this tournament."

New Zealand are the top-ranked team at the tournament at 57th. Trinidad and Tobago are 78th, UAE 84th and Saudi Arabia 107th.

"International football is always difficult no matter where you go and to play in the Middle East is tough," Herbert said.

"The pace and technical ability of all teams at this tournament will be high and that will certainly test us."

The All Whites squad will be announced later this week.
