Hool was next to cross for Takahiwai after a jinking solo run, but was unable to convert his four-pointer.
Desperation set in for Moerewa as they went wide to Jimmy Tauranga who was rewarded with his second try in the corner, leaving Bentley-Hape a difficult shot at goal which he was unable to convert.
With 10 minutes to go, Takahiwai hooker Damion Murray was sinbinned for dissent and Moerewa charged down field only to be denied by strong goal- line defence.
The last act of the game came when second rower Mike Hauraki scored with Hool converting as the final hooter went.
Takahiwai coach Shane Hool noted it was a great team effort from his side, giving his player of the day choices to Hool, Tarau and loose forward Wiremu Te Iringa. For Moerewa, Shane Hool said the Tauranga brothers, Ransfield, TJ Williams, Simione Ata and Herewini Macgregor were standout performers.
