[4][9] Since 1993, he has toured internationally, performing with artists such as George Thorogood, Jimmy Barnes, The Neville Brothers, Ian Moss, Junior Wells, Little Willy Foster, and Joe Satriani.
[13] According to the Stuff Circuit documentary "False Profit," Te Kahika left the army after he was involved in a drunken brawl sparked by when he allegedly verbally insulted a colleague with a speech impediment.
[13] Te Kahika claimed that he left the New Zealand Police after they overlooked his admission that he had been caught smoking glue at the age of 16 years.
The venture received the support of Helen Clark, the former New Zealand Prime Minister and the head of the United Nations Development Programme.
Sport NZ and Auckland Council's economic growth agency ATEED later stated that they did not give Te Kahika permission to use their corporate logos in material pitching their support.
His social media posts and live broadcasts were initially circulated for his Facebook friends, but gained a wider following and reached 30,000 views by May 2020.
[25] Following a second outbreak of COVID-19 community transmission in Auckland, Te Kahika participated in an anti-lockdown protest in Aotea Square that had been organised by Facts NZ and the Kotahitanga Movement Aotearoa.
[28] In October 2020 it was revealed that Te Kahika's paid weekly interviews with New Zealand conspiracy theorist Vinny Eastwood had violated electoral law as they did not include a legally-required promoter statement.
[32] In a later post, he said that his figure of 200,000 was a mistake but stuck to his claim that Advance voters' ballots had been disqualified for writing comments and drawing smiley faces on them.
[33] On 26 October, Te Kahika severed ties with Advance NZ after its election failure, stating that he had decided not to continue with the party.
[41][42] In December 2021, Te Kahika criticised other groups and leaders opposing the Government's COVID-19 restrictions in a video livestream, alleging there was dissension within the movement.
Te Kahika also criticised the anti-vaccination group Voices for Freedom and farmer advocacy organisation Groundswell NZ for allowing only approved messaging on protest signs.
A Groundswell spokesperson emphasised that the organisation was focusing on advocating for farmers and rural New Zealanders and denied Te Kahika's claim that the group was aligned with the National Party.
[47] In April 2022, Te Kahika and his co-accused Vinny Eastwood pleaded not guilty to breaching COVID-19 alert level 4 lockdown restrictions banning public gatherings.
[48] On 23 August, Te Kahika and Eastwood's trial at the Auckland District Court began with Justice Peter Winter presiding.
[49] Following a three day trial, Justice Winter convicted Te Kahika and Eastwood of violating COVID-19 lockdown restrictions on 16 December 2022.
[57][58] Between August and October 2011, Te Kahika led a music tour to help The Salvation Army raise funds for families affected by the 2011 Christchurch earthquake.
This suspension accompanied an Advance NZ/NZ Public Party video falsely alleging that the New Zealand Government had passed legislation forcing people to take a COVID-19 vaccine.
[59][60] As leader of the NZ Public Party, Te Kahika advocated on behalf of a woman known as "L.K.," who was imprisoned in late August after she and her children breached managed isolation in Hamilton to attend her husband's funeral.
[28] An investigation by Stuff Circuit, reported in October 2020, found that Te Kahika had misrepresented the New Zealand Government as backing a feasibility study to install solar power in 20 hotels in Samoa.
[64] According to University of Otago religion scholar Deane Galbraith, Te Kahika's conspiracy theories about COVID-19 and the New World Order are rooted in evangelical Christian End Times theology.
[65] In June 2020, Te Kahika made remarks in a Facebook Live video criticising the formation of Israel and propagating conspiracy theories related to the Rothschild family and Jewish control over the global financial system.
