Manager Robert Calvo and his men were ahead within the first five minutes against the Northern Champions when Michel Kaltak struck.
It was the perfect start but things got even better just a few moments later as Noel Morris pounced to put Tafea two goals to the good in the eighth minute.
But, despite seeing their defence breached twice so early on, Vaum United refused to lie down and got back into the game in the 11th minute with a Karl Roy strike.
There was no further scoring action before the half-time break and Tafea continued to dominate most aspects of the play in the second spell.
They were rewarded when Natou found the net in the 71st minute and the game was all but over as a contest when substitute Francois Sakama hit Tafea’s fourth goal with just a few minutes of regular time remaining.
But Vaum came back strongly in the closing stages and got back on the scoreboard through former Amicale striker Kensi Saksak.
Another hopes of an unlikely comeback however were dashed in the 88th minute when Natou notched his second goal of the game.
“Obviously, it’s fantastic,” Tafea captain Richard Iwai said.
“We knew it would be tough and it was – I think we got lucky with a couple of the goals. But we’re delighted, we’ve worked so hard this week and it’s paid off today.
“We are happy to win the Bred Bank Cup for the second time and all credit to my players.”
Iwai, who was in charge of the Vanuatu team that competed at the OFC Women’s Nations Cup during September and October in Auckland, was pleased with the backing given to his team but believes the win was down to those on the pitch.
“The fans’ support means a lot but for me it’s never been the most important thing. The most important thing is seeing this group do well.”
He also had a word of thanks for Tafea’s defeated opponents.
“I want to thank Vaum United for a very good football display in the final.”
