Morrison has been picked to be an assistant referee at next month's World Rugby sevens tournament in Wellington.
He will run the touchline at Westpac Stadium on on January 28-29.
Morrison, who is originally from the top of the South Island, made his first-class debut earlier this year at Heartland level and has been reappointed to carry on refereeing at the same level next year.
North Otago's Nick Webster has also been appointed to continue at Heartland level next year.
Former Otago referee James Doleman has been selected to referee at the Wellington sevens. He is part of the international panel which referees at sevens tournament around the world.
Former Otago inside back Wayne Peters has stood down as a board member of New Zealand Rugby. Peters had been on the board since 2009, the longest-serving current member of the board.
A former chairman of the Northland Rugby Union, he had stood down so he can concentrate on a recent health issue.
New Zealand Rugby is not waiting long to get a replacement.
It is calling on nominations from its 26 unions and will appoint someone to replace Peters by the end of the
week.
