They were the icing on the cake in one of Wanganui's finest efforts at the championships.
Spencer and Schwietring - part of a record 41-strong Wanganui High School squad - won the under-16 double sculls; Nga Tawa Diocesan duo Nugent-O'Leary and Gowler took out the under-18 version.
In addition, Nugent O'Leary clocked a remarkable second, two fourths and a fifth place in A finals; Gowler added a second, fourth and fifth; and Spencer had second and sixth placings.
And, of course, if you are at the top in New Zealand rowing, you are pretty near the top in world terms such is the Kiwis' strong hand in the sport.
Is it too much to hope we will be cheering these girls on in Olympic finals in future? I don't think so.
Also note that all of them were coached by Ian Weenink of the Aramoho club.
The only remaining question: where were the boys?
