"Its been sudden death for us for the last three or four weeks. I get to training and there are only seven players available to train. Last week we had to use eight reserve grade players," Rikiti said.
"It's hard for [the reserve grade players] and hard for the regulars. It's a big step up for them and when they do something wrong, the regular guys have to work twice as hard."
Despite Pikiao finding themselves in a similar situation this week, Rikiti said he was confident the team could still make the semifinals and eventually the finals on August 11.
"The only saving grace for us is having home advantage. If we can get our home crowd behind us it will make a huge difference."
But Rikiti said his team will have to lift their performance.
"We are way below par right now and I know Taupo are a strong side. They are a young Pacific side. They are a fit, rangy side and I have a lot of respect for that side," Rikiti said.
"They like to move the ball from side to side and have plenty of speed out wide. But I think we have a good game plan for them. It's all about pride for us. If we go out there and play to our plan we can beat them."
With key players such as fullback Connor Hohepa (neck), halfback Bully Tahuriorangi (hamstring) and Ivor Thomas (chest) out with injury, Rikiti has had to turn to his captain Jason Kameta and five-eight Pirikawana Taiatini to take more of the workload.
"Jason is an old work horse you know will work non-stop and Papa [Taiatini] has really stepped up since Bully has been injured."
