Due to the withdrawal of Vanuatu's Port Vila Sharks, Waitakere was given a berth in the inaugural OFC Champions League, for 2007, as NZFC premiers.

Taking this championship qualified United to compete in the 2007 FIFA Club World Cup in Japan, where they lost in the 'play-in' match to Sepahan 1–3.

Waitakere United defended their championship in capturing the 2007–08 OFC Champions League, defeating Kossa in the final 6–3 in goal aggregate.

During this season, Douglas Field was under extensive renovation forcing Waitakere United to play most of their home fixtures at Fred Taylor Park in Whenuapai.
