Hef had 15 minutes off the pine and Andrew 10.
"I was very proud of our boys tonight. They showed a lot of heart," NOBM head coach Craig Gowler said after the match.
"We led 24-0 at halftime and that woke Auckland up. While we took all of our opportunities we were fortunate Auckland bombed a few of theirs and we had a few calls go our way," Gowler said.
Regular outside back and third-string halfback Sam Weber was instrumental in the victory playing in the No 9 jersey. Gowler said his two Magpies halfbacks, Ellery Wilson and Zac Donaldson, can expect plenty of hot competition from Weber when the Nash Cup competition begins on March 24.
Matt Gardner had a huge workrate at No 8 and second five-eighth Paul Bickle was classy.
"To get through this game with 19 players was a huge achievement. Fortunately we've got another three arriving tomorrow," Gowler said referring to winger Michael Buckley, centre Shae Tucker and flanker Willie Benson.
Weber, Gardner, winger Sonny Lilo and fullback Liam Edwards scored tries for NOBM last night and veteran centre Migao Lauano kicked two conversions. Hutt Old Boys Marist pipped Marist Albion of Christchurch 22-20 to secure their berth in tomorrow's midday final.
