Samoa lost 38 - 8 to the Kiwis last weekend, while Tonga thrashed Scotland 50 - 4.
New South Wales hard-man Andrew Fifita says they're definitely not underestimating Toa Samoa.
"They're pretty packed. They're a good strong team and that's going to really challenge us," he says. "In saying that, we'll be ready for it and we can't wait for Saturday."
Former Warriors winger Manu Vatuvei says although Tonga won their last game convincingly, they know Samoa won't back down.
