Along with Hayward, first five-eighth Arana Murphy operated well in the Hastings backline and dictated terms with aplomb. Lock Sean Baker ruled the lineouts and No 8 and captain Liam Udy-Johns and flanker Daemon Brough were commanding figures in the loose.
Baker, Brough, Udy-Johns and wingers Michael Naitokani and Joeli Rauca scored tries for Hastings and Murphy kicked three conversions.
While there were plenty of bumps and bruises to deal with after the final whistle Bird said there were no major injuries after his team's fourth consecutive win.
Bird pointed out there was able to be more dialogue between the Japanese referee and his players than there was in their previous outing.
"While the ref's English wasn't perfect it was definitely better than the non-English referees we had in previous games."
Semifinals are scheduled for tomorrow and the final on Saturday.
Bird said HBHS were scheduled to meet the winner of the quarter-final between Osaka and hosts Fukuoka in their semifinal.
