New Zealand, coming off a victory at the previous tournament in Cape Town in December, will hope captain Scott Curry and forward Sam Dickson can shake off injuries suffered in the Samoa match.
It may provide more opportunities for talented 18-year-old Etene Nanai-Seturo, who scored against both Russia and Samoa in his tournament debut.
Australia survived two tight matches against the United States (26-19) and Scotland (24-21) to be among four unbeaten teams.
The others are defending series champions South Africa, Argentina and Fiji.
