New Zealand's most senior referee Chris Pollock has announced his retirement from international rugby.
Pollock has returned to full-time teaching in in his home province, Hawke's Bay.
New Zealand Rugby's general manager of rugby Neil Sorensen paid tribute to Pollock and said the 43-year-old, who was one of only two New Zealanders – alongside Glen Jackson – who refereed matches at the recent Rugby World Cup in England, had made an important contribution to New Zealand, and international, refereeing.
"Chris has given a huge amount to this game both at the provincial and international level," said Sorensen.
"This year, he was our most experienced referee on the field with 192 first class matches to his name including the 22 internationals tests, two Rugby World Cup tournaments, 70 Super Rugby matches, and nine Ranfurly Shield challenges.
"We are very grateful to Chris for the huge contribution he has made to the game.
"We hope he will continue to be involved in rugby and share his knowledge and experience, with up and coming referees both at the provincial and national level."
