GAUNAVOU will defend the KK's Hardware Challenger Shield against Namotomoto-based Tovolea team at Prince Charles Park on Saturday.
The reigning champion has survived three challenges this season and will want to maintain its winning run in the competition.
Nadi rugby official Rusiate Ratakele said Tovolea would be aiming to wrest the title away from Gaunavou.
"Gaunavou has overcome three challengers so far this season and it will be interesting if they can withstand the pressure from Tovolea," he said.
"Tovolea has some players that have played in the Nadi team and they are capable of beating Gaunavou."
Gaunavou has been boosted with the inclusion of star players such as Samu Saqiqa, Sione Tanoa, Vilikesa Driu and Nadi skipper Viliame Ratute.
Ratakele said the side had prepared well for the battle.
