[6] In January 1982, Hannah and her daughters accompanied her husband Brian to Te Nikau Bible College near Paraparaumu, which was affiliated with Pentecostal and Charismatic movements.
[9] Around 2002, Hannah Tamaki founded the Healing Hands Ministry as a small organisation to earn money from the Destiny women's meetings and to support people undergoing treatment, particularly for cancer.
[10] According to the historian Peter Lineham, Hannah served as the "business brains" of Destiny Church, complementing her husband Brian who was primarily a visionary.
[11] Hannah played an active role in the leadership of Destiny Church, frequently leading worship and was always portrayed as the partner of her husband in all his ministries.
In addition, Tamaki received a salary due to Brian's view that wives should be paid for their ministry if they were working alongside husbands who were employed by the church.
"[18] Tamaki identified the legalisation of marijuana, euthanasia and late-term abortion as key motivating factors that spurred her decision to launch a new party.
[24][25] In addition, Tamaki advocated greater financial autonomy for Māori people, including a Māori-owned bank and Tūhoe ownership of Te Urewera.
She also called for government funding of Destiny Church's Tu Tangata, Man Up, Legacy and Youth Nation volunteer programmes.
[27] Tamaki herself secured 1,171 votes in the Waiariki electorate, coming third place behind the Māori Party's Rawiri Waititi and Labour's Tāmati Coffey.
[30] In March 2021, Hannah and Brian attracted media attention after the couple left Auckland while the region was under an Alert Level 2 lockdown and visited Rotorua before traveling to Te Anau in the South Island.
The couple's actions were criticised by COVID-19 Response Minister Chris Hipkins, Mayor of Invercargill Tim Shadbolt, and Director-General of Health Ashley Bloomfield.
Tamaki spoke in the absence of her husband Brian, who had previously been arrested for leading two anti-lockdown protests in Auckland and was on bail pending trial.
[36] Stuff had earlier identified Tamaki's husband Brian as the "founder and architect" behind "The Freedoms & Rights Coalition," which had staged several anti-lockdown protests across New Zealand.
[40] On 17 January 2022, Tamaki's husband Brian was arrested and remanded at Mount Eden Correctional Facility for violating his bail conditions by attending the Christchurch protest.
[43] In early November 2024, Tamaki, Brian, Jennifer Marshall, and Kaleb Cave faced trial at the Auckland District Court on charges of organising a series of large public gatherings between September and October 2021 in contravention of Level 3 COVID-19 restrictions at the time.
[44] The Tamakis and their co-defendants were defended by Ron Mansfield KC, who argued that they did not intentionally break lockdown rules and that the group were unfairly targeted by Police.
[47][48] On 28 September 2023, Hannah and her husband Brian led a TFRC protest against a scheduled "Agenda 2030" conference at the New Zealand Parliament in Wellington.
Similar sentiments were echoed by former League president Denise Ewe, who claimed that Hannah's support was only coming from "Destiny-grown branches.
However, the League's executive deemed the Destiny-affiliated branches as unconstitutional since they were formed on a sectarian bases and declined to send voting papers to them.
The League also distributed voting papers without Tamaki's name and suspended links with those branches and church members pending an inquiry.
[60][61] Hannah welcomed the Court's decision reinstating her on the League's ballot and allowing three of the Destiny-affiliated branches to participate in the leadership election.
The League subsequently revised its policies allowing its National Executive the power to vet presidential and vice-presidential nominations as well as membership applicants.
