As the score suggests, Saturday's victory was another admirable performance from the hosts, who have scored 778 points in their 13 outings while conceding 50.
Hastings ran in nine tries and again produced some impressive ball handling and support play in difficult weather conditions, but delighted manager and former Magpies halfback Jason Bird said it was the defensive work of his troops which was the most pleasing aspect of the victory.
"To keep a good team like Rotorua to zero was a good effort."
Impressive No 8 Devan Flanders was again full of authority in all aspects of play and displayed his versatility by playing the final eight minutes on the wing.
Winger Kini Naholo was again dangerous and scored two tries to take his season tally to 32. Naholo and flanker Jeriah Mua have both been named in the Chiefs' under-18 training squad.
Fullback Danny Toala and first five-eighth Lincoln McClutchie again proved why they are in the frame for New Zealand Secondary Schools team selection.
Rotorua's best players were lock Stephen Schwenke and second five-eighth Tom Ale. Rotorua co-coach and former Maori All Black and Bay of Plenty Steamers halfback Ruki Tipuna was full of praise for the Hastings outfit.
"I've heard all about your team and read about it. Today I saw it for myself ... you don't have a lot of stars but you play so well as a team, so clinical and so well structured," Tipuna told Bird.
The team expected to push Hastings in the Super 8, Hamilton Boys' High School, beat Napier Boys' High School 55-8 in Napier. The hosts - who were missing eight regular starters through injury including captain and flanker Josh Bokser, and vice captain and halfback Humphrey Sheild - trailed 13-3 at halftime.
Hooker Patrick Teddy scored Napier's only try off a lineout drive and fullback Nikau McGregor kicked a penalty.
