It was highlighted from almost the moment of entry of opening performers and Auckland group Te Manu Huia, dedicated to Maori performing arts legend Dr Ngapo Wehi, who died last July.
Te Manu Huia, following senior group and five-times winners Te Waka Huia into the festival for a ninth time, are tutored by family of Dr Ngapo Wehi QSM, whose festival history dated back to when he and wife Pimia took Gisborne club Waihirere to the first title in 1972 in Rotorua.
Moving to Auckland they also took Te Waka Huia to their first title, at Christchurch in 1986.
Later in the day members of Porangahau-based Tamatea Arikinui loomed strong in their support for Tauranga-based Mataatua representatives Tutara Kauika ki Rangataua in one of many of the displays of "tautoko" from the audience, again paying respects to a past champion of kapa.
Long-time Tamatea Arikinui member Doc Ferris, who made up to a dozen trips home from Nelson to Porangahau in the last months of his group's preparation for its performance on Saturday, said the spontaneous response was a tribute to former Tauranga group leader Te Awanuiarangi Black, who died less than three months ago.
"A lot of our whanau have a lot of links, and his kids were on the stage," Mr Ferris said.
In kind, performers paid their respects to the host area, parts of Kahungunu haka Tika Tonu spliced into more than one performance.
The festival has attracted a record 47 groups. Of them, 16 more will on stage today, including defending champions and two-times winners Te Kapa Haka o Te Whanau-a-Apanui, and the first Hawke's Bay group, Wairoa-based Te Rerenga Kotuku.
Another 16 will perform in the last preliminary rounds tomorrow, five-times winners Te Waka Huia and Waihirere, and Hawke's Bay groups Ngati Kahungunu ki Heretaunga and Tamatea Arikinui.
