The game was well and truly Rangitoto's throughout, with a 25-12 first quarter lead being a testament to their ball movement and quality defence, as well as their dominance inside.
Westlake were forced to regularly throw multiple players at Wynyard, who responded with a mix of bruising post-ups and adept kick-outs to open shooters.
Rangitoto snared 48 rebounds to Westlake's 34, and had 58 points in the paint to Westlake's 28, as last year's runners-up couldn't get anything to fall, shooting just 31% from the field, 12% from deep (2/17) and 52% at the line.
Westlake did manage to make it a nine-point game at the half but a third quarter run blew the scoreline out to a comfortable 15 point margin where it stayed steady for the remainder of the contest.
The win doubled as revenge for 2013 for Rangitoto, where their side led by Derone Raukawa and Luuk Witteveen fell to the Jaylen Gerrand, Jack Salt and Josh Howe Westlake trio in the final.
For Rangitoto, Wynyard was capably assisted by the excellent Dan Fotu (16 points, eight rebounds), Isaac Davidson (13 points, five rebounds and three assists) and Brayden Inger (10 points, nine rebounds).
After back-to-back match-winning performances of 47 then 50 points, Matt Freeman had 28 points and nine rebounds but could only shoot 11/31 from the field and 1/7 from deep as Westlake's great tournament fell short.
St Peters Cambridge 64 Wellington Girls College 54
In the girls final, St Peters bounced back from a sluggish offensive showing in their semifinal win over Hamilton Girls to take down an impressive Wellington Girls side and make it a double triumph after earlier this year winning the national 3×3 title.
In her last game for the school, Krystal Leger-Walker found her shooting touch with several early threes as St Peters edged out to a 18-16 lead after the first quarter, and she was notably helped out by Kendall Heremaia in the second quarter.
Despite Wellington's first-half struggles, they only found themselves down by one at the break. Their star duo in their semifinal win over Christchurch Girls - Tegan Graham (14 points) and Shalae Salmon (13) - did enough to keep them in contention, but were kept relatively in check by a St Peters side who made up for their lack in size with a strong mix of effort and smarts.
The lead stretched out to four after three quarters and it remained at a close distance throughout the final quarter, before Heremaia coolly slotted four free-throws to end the contest and give St Peters their first national title.
Heremaia was the game's leading scorer with 17 points and eight rebounds, Leger-Walker had 14 points, eight rebounds and six assists while her sister Charlisse added 13 points and nine boards.
