Running for offices

In 2004, he unsuccessfully contested the mayoralty of Christchurch, New Zealand, placing 5th out of 10 with 1.9 per cent of the vote (1665 votes).^{[citation needed]}

In 2005, he was the tenth-ranked list candidate for the Direct Democracy Party.^[10] The party, which only contested the 2005 general election, did not achieve representation.

He unsuccessfully contested the Christchurch mayoralty again in 2007, running this time under the National Democrats ticket.^[11]

In 2013, Chapman ran again for the Christchurch mayoralty, but was unsuccessful, securing 499 votes. He also ran for the Ferrymead-Pegasus Local Board, securing 641 votes, but was also unsuccessful there.^[12]

Turning his back on politics

After the 2019 Christchurch mosque shootings Chapman said he had "fallen out" with others in groups he used to belong in and "turned his back" on them to focus on family and religion.^[13] This was disputed by a holocaust historian, who said his statement was "an object lesson in the tactics these groups use to legitimise themselves through media manipulation".^[14]

COVID-19 pandemic

On 20 August 2021, Chapman and two other individuals appeared in the Christchurch District Court after they broke COVID-19 lockdown restrictions to protest those restrictions the day before in Christchurch. The three individuals were remanded in custody on charges of failing to comply with restrictions under the COVID-19 Public Health Response Act 2020.^[15][16]

2023: Plots against Pride event and arrest

Chapman was involved in 'Room 102', also called the 'Robert Grey Life Centre', a Christchurch-based group of conspiracy theorists and extremists. The group targeted an event where drag queens read stories to children. Ultimately 50 people protested the event, with an equal number of counter-protestors.^[17] Chapman has used group's headquarters to hold survivalist workshops and martial art sessions.^[18]

On 20 February 2024, Chapman was sentenced to six months' community detention and six months supervision after he plead guilty to unlawful possession of Norinco semi-automatic rifle. This was one of the semi-automatic weapons banned following the Christchurch mosque shootings. He also plead guilty to possession of ammunition and parts for a rifle.^[19]

Court documents showed that Chapman had recently met with ex-marines and soldiers in the United States and that he had formed a new survivalist group in North Canterbury.^[20]

National Front

Chapman is a former leader of the New Zealand National Front,^[1] leading the organisation from 1997 to 2005. In 2005, he resigned his role as the leader of the National Front. He said in interviews that his children were being shunned at school due to his activities. He also cited the harassment by left-wing anti-NZNF groups as a factor in his departure.^[21]

Right Wing Resistance

In 2009 Chapman founded the Right Wing Resistance, a neo-Nazi group,^[22] in Christchurch with a group of white nationalists. Chapman reportedly knighted the members with a sword after they recited a pledge. The group's insignia was a skull over a Wolfsangel, with the notation "NA 14". Its introduction to the New Zealand public was its Christchurch street patrols in October 2009, which appeared to target Polynesian youths.^[23] RWR members engaged in street patrols in New Brighton with the stated purpose of preventing vandalism by youth street gangs. The mayor of Christchurch denounced their vigilante behaviour. Its street patrols included from 5 to 15 members, who had shaved heads.^[24] Also in October 2009, Chapman organized a rally at the Wellington cenotaph.^[2]

The group attempted to recruit further members in Auckland.^[25] Press coverage resulted from distributions of flyers comparing immigration to an invasion, which were called "despicable" by the Race Relations Commissioner.^[26][27] It also helped organise protests and other street activities alongside the National Front.^[28]

During the 2011 general election campaign, members of the group disrupted a candidate's election meeting in Christchurch appearing in military-style clothing. They stated that they would protest at polling booths throughout New Zealand on election day; however, this did not happen.^[29]

After the March 2019 Christchurch mosque shootings Chapman said he was no longer involved with this group.^[13]

Right Wing Resistance was reported in November 2019 to have chapters in Australia, Sweden and Scotland.^[30] There is an Australian far-right extremist group called Right Wing Resistance Australia,^[31][32] said to have "international connections".^[33]

Survive Club

Chapman founded and led the Survive Club, a survivalist group that denied being a militia and having any racist ties despite the histories of some of its members.^[34][35]
