For a time, it became a shootout between Gerrand, who scored 41 points in their semifinal win over Rosmini, and Rangitoto sharpshooter Derone Raukawa, who had two 40-point efforts earlier in the tournament.
Gerrand scored 15 points in Westlake's second-quarter burst, but was able to share his load among his teammates, especially after Matt Freeman returned from his foul-imposed spell on the bench.
Once Davidson's early threat passed, Raukawa became Rangitoto's only real offensive weapon, finishing with a game-high 35 points, including five three-pointers.
Gerrand led his side with 26 points but had support from Howe (22 points/15 rebounds) and Salt (14 points/16 rebounds).
A production line for the Tall Blacks in recent years, Westlake have now won the title five times with current or future internationals including Corey Webster, Tom Abercrombie, Rob Loe, Tai Webster and most recently, Salt in their ranks.
Rosmini finished third to complete a clean sweep for North Harbour schools in the boy's championship.
Meanwhile, forward Tessa Boagni capped a remarkable sporting year leading Christchurch GHS to a runaway 65-46 win over Rangitoto to capture the girls' title.
Boagni dominated her head-to-head match-up against Tall Fern rival Penina Davidson from the start to lay the foundation for the southerners' success and earn MVP honours in the process.
Earlier this year Boagni was named MVP at the national SS volleyball tournament at the same venue after guiding Christchurch GHS to a surprise runner-up finish.
Boagni scored her team's first eight points as they established an early 10-3 advantage. Nine unanswered points to start the second quarter - forward Polly Hill scored seven of them - stretched the lead out to double figures. By halftime Christchurch were 38-23 ahead.
The lead reached 25 points late in the third period, and while Davidson and Ella Fotu rallied their side within 13 down the stretch, it was too late to change the result.
The victory also earned Christchurch the distinction of being the only unbeaten team at the week-long tournament.
Boagni finished with 28 points/17 rebounds, while Hill had three three-pointers in her 14 points, and Gabriela Edmondson contributed eight points/13 rebounds and six assists.
Davidson battled hard for her 20 points/18 rebounds and Fotu had 15 points, but the pair shot 16/46 between them.
