INCIDENT: New Zealand Cricket says Tim Southee did 'nothing untoward' on the flight from Sydney to Dubai on route to the World Cup.

Black Caps team manager Dave Currie says reports of a player behaving in a "lewd" manner toward a woman on an international flight were not factual and the matter would not be taken any further.

A passenger on the flight between Sydney and Dubai told Newstalk ZB the incident involved a Black Caps player and a woman he met on the plane.

The passenger described it as the "worst possible sort of lewd behaviour", the station reported.

Currie confirmed to NZPA the player was Tim Southee but said he had investigated and established the reports were not factually correct.

"We have investigated and spoken to a number of other players and we are satisfied that nothing untoward has happened."

Currie said the woman had made no complaint.

New Zealand Cricket chief executive Justin Vaughan told TV3's Campbell Live he had spoken to Southee, who was adamant nothing untoward had happened.

"I've spoken to Tim, I've also spoken to the team manager Dave Currie, I've spoken to (captain) Dan Vettori and a number of other players" Vaughan said

"It appears pretty innocent really.

"I think Tim met a female passenger and struck up a conversation They spent a bit of time and had a drink together on the plane.

"At some stage the female passenger came to Tim's seat and perhaps spent a maximum of 30 seconds with Tim, and there may well have been, dare I say it, a kiss on the cheek, but that was it. She went back to her seat, and Tim is adamant that nothing inappropriate, nothing untoward, occurred."

Vaughan said a number of other players had supported Southee's version of events

The team's media manager, Ellery Tappin, said he was "dumbfounded" by the amount of attention the reports had garnered.

"We've done a thorough investigation and found absolutely nothing substantial, so are incredibly surprised by the amount of attention it's generated and are all a bit dumbfounded, to be perfectly honest, about how this has escalated," he said.
