Waikato are young, hungry, but just a little scattergun. Their coach Sean Botherway spoke about them being "too panicky" at times. They will be a threat in 2016, but not this season.
Wellington, missing Cory Jane and Brad Shields, were not roaring on all cylinders, but they did register the seventh win by a Championship union over a Premiership side in 2015.
Thrush scored the opening try, galloping over from 25m and showing some startling acceleration. The high-stepping blindside flanker Vaea Fifita made a superb break to set up his hooker Leni Apisai for the second.
"A win's a win. After (the loss to) Otago, we wanted to focus on this game and come out with the W. We had good opportunity in the first half, slipped a bit in the second, but our defence was good," said Savea. Both sides lamented a plethora of turnovers which hindered their attacking fluency.
"Wellington really controlled the middle part of the game, but we allowed them to get away to too big a lead," said Waikato skipper Weber.
Mooloo blindside flanker James Tucker evoked memories of the 1992 'Hand of Purvey' by raking a scrum ball back with his left mitt. He got away with it, as former Waikato front-rower Graham Purvis did at Eden Park in the 1992 NPC semifinal against Auckland.
Next up for Waikato is Counties Manukau in Hamilton on Friday night, while Wellington have the shortest turnaround permissible, just three days until they host Hawke's Bay in a top of the table Championship contest on Wednesday night.
Wellington 21 (Jeremy Thrush, Leni Apisai tries; Jason Woodward con, 3 pen)
