Michael Austin's heart-melting cor anglais solos in The Swan of Tuonela were a predictable highlight, but throughout, the composer's sonic ingenuity came alive through Inkinen's spirited championing.
The standing ovation and tickertape that followed might well have been a response to the particularly glorious homecoming of Sibelius' mythical Nordic hero.
Earlier in the evening, Canadian violinist Karen Gomyo also received a standing ovation for her Beethoven Concerto, but without streamers.
Wellington critics were disappointed with her projection in the Michael Fowler Centre but, in Auckland's acoustically superior town hall, Gomyo's Aurora Stradivarius lived up to its nickname.
With Inkinen laying out a solid architectural base for Beethoven's first movement, Gomyo was free to explore the expansive allegro in fascinating detail, some of it unexpected.
Beethoven's boisterous Finale benefited from Gomyo's gusto and pinpoint accuracy, aptly introduced by her brilliant delivery of one of Nathan Milstein's crackling cadenzas.
