New Zealand rugby referees Chris Pollock and Glen Jackson have been given games in next year's Six Nations competition.
Jackson will control the Scotland-Wales match in Edinburgh in early February and Pollock will officiate in Italy's Test with Wales in Rome in March.
Jackson, Pollock and Mike Fraser also have roles as assistant referees during the Six Nations.
New Zealand referee Ben Skeen has two Six Nations tests as TMO.
World Rugby match official selection committee chairman John Jeffrey is emphasising the importance of performance during the Six Nations.
Jeffrey says with an eye on Rugby World Cup 2015, their focus continues to be clear and consistent decision-making and the highest standards of physical conditioning.
He says selection for RWC will be made shortly after the Six Nations so these will be important opportunities for the referees, ARs and TMOs.
The former New Zealand referee Steve Walsh, who is now based in Australia, gets two Six Nations matches. Walsh will take charge of Wales-Ireland and England-France.
