The New Zealand Sevens team edged further ahead of arch rivals Fiji in the overall standings after finishing third at the Japan Sevens.

Australia won the tournament, defeating Samoa 28-26 in the decider.
Tietjens says the England win is vital for their title hopes.

New Zealand lead Fiji by six points with tournaments in Scotland and England to round off the series next month.
