The co-founder of Te Pāti Māori died on Friday after suffering a stoke and is lying in state at Whangaehu Marae near Whanganui before her burial tomorrow.
Eru Kapa-Kingi, one of the organisers of November's Hīkoi mō te Tiriti, said he and fellow organisers would be congregating at the marae gates ahead of this morning's pōwhiri.
Anyone else wanting to pay their respects should join them, he said.
"We put out a social media announcement... to put the tonu out there for anyone else who might be looking for an opportunity or an iwi to join to honour whaea Tariana as well as the kaupapa she carried."
A hīkoi in opposition to Act's Treaty Principles Bill, which culminated in 40,000 people descending on Parliament in November last year, was inspired by Dame Tariana's advocacy for Māori rights, Kapa-Kingi said.
Dame Tariana is perhaps best known for her split from the Labour Party over the Foreshore and Seabed Act, which led to a protest march on the Beehive in 2004.
She resigned her seat and left the party before winning the subsequent Te Tau Hauauru by-election and returning to Parliament representing the newly formed Māori Party, as it was then known.
That took courage, Kapa-Kingi said.
"I am absolutely obligated to honour and to pay tribute to our whaea because without her example, without her bravery, there's no way we could have even imagined the action that we took recently."
Visitors and dignitaries from around the motu were welcomed onto Whangaehu Marae over the weekend.
The marae opened to the motu yesterday. Te Arikinui Kuini Nga wai hono i te po, the Māori Queen, led manuhiri (visitors) in a pōwhiri in the morning.
Sir Pita Sharples, who co-founded Te Pāti Māori alongside Dame Tariana, would arrive today, whānau spokesperson Che Wilson said.
