The Whangarei event will be held in the Whangarei Hospital cafe from 10.30am to 2pm. It will include the result of tendered bids for a tewhatawhata (stick) and patu (club) carved by kaumatua Ned Peita, spot prizes and entertainment from the kapa haka group of Maori language immersion school Te Whare Kura o te Rawhitiora, where Ms Muriwai was a foundation pupil.
Prizes will be offered for the winner of a short quiz on bronchiectasis and a raffle will be drawn for a patchwork quilt made by Christine Cook.
Mr Muriwai said the two carved taonga had been auctioned together as "they were made together and they will stay together".
The baby quilt donation was made after he stopped to admire a quilt being sewn by a visitor to the hospital, where he works. Unaware she was talking with Ms Muriwai's father, Ms Cook told him she had read the story of a young Northland woman who died of bronchiectasis but had led an inspirational life.
"She told me, 'When I've finished this piece I'm going to donate it to the foundation she started'," Mr Muriwai said. He said he was very proud to tell her that had been his daughter.
Ms Muriwai, who set up the Northland Bronchiectasis Support Group in 2013, was passionate about starting a national foundation to support families and back more research.
While her illness affected her severely, it did not define her - and during her too few adult years she was a beauty queen, budding local politician, campaigner and advocate.
In one interview with the Advocate, she said: "You have to take what your challenge is and use the wisdom gained from it to get on with life."
After being presented with a Bravery Award in the Asthma Foundation Achievers' Awards in Wellington by Governor-General Sir Jerry Mateparae in March 2014, she cheekily asked him to be patron of the Bronchiectasis Foundation she would one day set up.
Ms Muriwai died only months later and her parents Ana Sadlier and Mr Muriwai, with other supporters, completed the task she had begun.
True to his word, Sir Jerry became patron and officially launched the foundation in Whangarei on April 7, 2015.
