For the 187.5cm (6ft 2in) tall Sammy Murphy, the year-long development programme will be old hat as she has been through it this season and this weekend is away attending the 2013 edition of the national camp in Auckland.
However for 15-year-old Tamati it will be her first year receiving this level of attention, which is designed to give players an inkling of the commitment and skills required to become an elite player.
Harrison is one of nine umpires chosen for the officials' programme and Lisa Murphy said it was wonderful to have a Wanganui umpire included, as Harrison had completed her regional theory assessment this year as well.
Both Murphy and Tamati were part of the successful Phillips Electrical Wanganui High School A1 team which swept both the secondary school and Premier 1 championships this season, and represented Wanganui at Under 17 and Under 15 level respectively.
