Townsville, without the services of starting centre Ben Allen who had a stomach bug, were out-rebounded 42-26.
But the night was looking a little brighter when they shot off to a 9-2 start thanks to eights points by Ervin, but some poor shot selection allowed New Zealand within two at quarter-time.
The teams traded blows in the second period, but a late Abercrombie three-pointer from the corner ensured the Breakers edged ahead 40-35 at the main break.
When Jackson crossed over his man before shooting a fade-away at the top of the key in the third the Breakers were up by 10 for the first time and looked to be pulling away.
But Townsville's perimeter barrage brought the game to life as the home side threatened to overrun the defending champs.
Then Bruton, the master of big shots, nailed a transition three to give the Breakers some breathing space and swing the momentum.
Crocs forward Jacob Holmes committed a technical foul on the next play and the Breakers were ahead by eight, holding off the home side with some suffocating defence from there.
