Diocesan School duo, Sienna French and Halle Rankin Hastie, are synchronised trampoline stars. Having recently won gold for synchronised trampoline in their Open Sub-junior (13-15yr) category at the New Zealand national competitions, their next stop is representing New Zealand at the 2017 World Trampoline Championships in Bulgaria this November.

Twelve-year-old Sienna French is the youngest girl to be selected for the NZ team. She is also unique in that she is competing in three categories – individual, double minis and synchronised.
