"Annie was able to draw on her tikanga to bring individuals and agencies together to focus on improving the lives of whānau, community, hapū and iwi. Her leadership, integrity, trusted advice and selfless dedication to Tairāwhiti and the Hawke's Bay community enabled her to touch the lives of many," he said.
He said her perspective and voice were constantly sought, and her word was trusted by business, iwi, council leaders and colleagues.
"We will miss her guidance, her friendship, her quiet dignity and her presence. Annie may have had a quiet voice, but she could command a room."
Among others who had arrived at Moteo, where the tangi ends on Tuesday have been MPs and departmental heads, and mayors and councillors.
Ikaroa Rawhiti MP Meka Whaitiri said in a Facebook post she was "absolutely devastated and heartbroken with the sudden and sad news of Annie Aranui's passing".
She described her as "the consummate Senior Māori Public Servant delivering gains for our people in the social development and employment area", and said that as MSD's Regional Commissioner she had a can-do attitude. "Always advocating for Māori interest and never shying away from doing more."
The tangi ends with the final service on Tuesday starting at 11am. Burial will be at Paparakaitangi urupā.
