"We need to take a good, hard look at ourselves.
"We're all in agreement that it wasn't anything other than a lack of pride and a lack of effort."
That deficiency was apparent during a horror second quarter that saw the Breakers blown out.
The Kiwi club have long prided themselves on winning the rebounding battle but Adelaide were handed an open invitation on the offensive glass.
"It all stemmed from that second," Henare said.
"We got outplayed, out-hustled, out-rebounded and, after that second quarter, we were pretty much digging ourselves out of a hole."
The Breakers brightened up in the second half, with new import Charles Jackson finishing with a handy contribution of 12 points and seven rebounds, but never managed to reduce the deficit below 15.
Both Abercrombie and Pledger could return for Sunday's home opener against Townsville.
