Australia and New Zealand remain undefeated on the penultimate day of the team tournament at the Oceania Badminton Championships to set up a grand slam finish tomorrow in Auckland.

Australia currently hold a points difference lead atop the standings in the round-robin as the top two sides both have five wins from five at the Auckland Badminton Stadium.

They began the day's action with a 4-1 win against Tahiti.

Tahiti's sole point came courtesy of Rémi Rossi, who beat Jacob Schueler 21-19, 21-17.

His compatriots did not fare better, however, as they all fell victim to straight set defeats.

New Zealand then responded by whitewashing the Northern Mariana Islands 5-0.

Women's singles champion Shaunna Li delivered the hosts' best performance of the tie as she dominated Jeanelyn Cardinio 21-6, 21-10.

The next session saw New Zealand in action again as they faced Tahiti.

Rossi was on form again but he could only do so much for his team as they suffered another 4-1 loss.

Both Australia and New Zealand then beat New Caledonia 5-0 in their final matches of the day.

The Australians hold pole position going into the final match courtesy of a positive points difference of 674 compare to New Zealand's plus 603.

Despite the defeats, New Caledonia occupy third place with their last match scheduled for tomorrow against Tahiti.

The Cook Islands are also set to face Tonga in the session.
