The touring Junior Waratahs rugby side will unleash tonight the potential 20 year old Namatakula lad Ratu Nasiganiyavi has when they take on Nadi at Prince Charles Park.

Coach Chris Hickey said tonight's showdown will be the biggest test in Nasiganiyavi's rugby career as he will face a test with the provincial rugby champions of Fiji.

Hickey said Nadi should provide Nasiganiyavi, who is 193 cm tall and 125kg, a taste of top level rugby in Fiji.
