First term, 2014–2017 Parmar was announced as a National Party candidate in June 2014. In her maiden speech of 28 October 2014, Parmar stated her values of "strong, caring families and communities, personal responsibility, and equal citizenship and opportunities" and set out her priorities for the science sector and small businesses. In her first term, during the final three years of the
Fifth National Government, Parmar was a member of the social services committee and transport and industrial relations committee. In 2017, she was briefly deputy chair of the transport and industrial relations committee. The bill, which proposed to require newborns to be enrolled with a general practice before the age of 6 months, passed its first reading with support of all parties and was referred to the health committee. At its second reading in mid-2018, the bill was voted down with members in the majority arguing that enrolment of newborns with general practices is already required without legislation.
Second term, 2017–2020 In her second term, when National formed the official opposition, Parmar was appointed the party's spokesperson for research, science and innovation from 2017 to 2020, as an associate spokesperson for economic development from 2018 to 2020, and as spokesperson for statistics in 2020. and for financial security for Crown Research Institutes. She supported legislative change to enable gene-editing as a means to reduce greenhouse gas emissions. Parmar's second member's bill, the Patents (Advancement Patents) Amendment Bill, was debated in August 2018. It proposed to create a second-tier patent with lesser eligibility requirements and protection compared to the standard patent. The bill attracted attention from local patent attorneys, the software industry, and from overseas jurisdictions but was ultimately unsuccessful at its first reading. Parmar worked with a Mt Roskill local amenity,
Stardome Observatory, to help fix an issue that all Auckland Regional Amenities faced in regards to their financial reporting requirements. Parmar sponsored a private bill, the Auckland Regional Amenities Funding Amendment Bill, which was supported by all parties and became law on 2 July 2020. In response to comments by
New Zealand First MP
Shane Jones in which he stated that immigrants that criticised immigration policies should "catch the first plane home," Parmar sent a letter to Prime Minister
Jacinda Ardern expressing her concerns. On the 150th anniversary of
Mahatma Gandhi's birth, Parmar ran a petition for his statue to be installed in Auckland to acknowledge his legacy. At the time of launching her petition, she said "that a statue of Mahatma Gandhi is not just about India and New Zealand, and/or Indians in New Zealand, it is about honouring his legacy – the legacy that is ever lasting and is influencing civilised societies all around the world." Parmar was defeated in
Mount Roskill at the
2020 election and the National Party did not win enough support for her to return as a list MP. She sought the National candidacy in Mount Roskill,
Upper Harbour, and
Maungakiekie ahead of the
2023 general election but was not selected.
Third term, 2023–present On 31 May 2023, Parmar announced her return to politics, switching her party affiliation from National to
ACT. That same day, she was confirmed as the ACT candidate for
Pakuranga. In July, ACT placed her ninth on its party list. During the
2023 New Zealand general election held on 14 October, Parmar was elected to Parliament on the ACT party list. She also came third place in the Pakuranga electorate, gaining 1,298 votes. As ACT's education spokesperson, Parmar objected to the
University of Auckland's designated
safe spaces for
Māori and
Pasifika students in late March 2024. She argued that the policy was racially discriminatory, divisive and failed to address historical injustices faced by ethnic minorities in New Zealand. On 24 March 2025, Parmar criticised the University of Auckland's compulsory Waipapa Taumata Rau first year course, which focuses on Māori culture and the
Treaty of Waitangi. She said that a course focusing on New Zealand-specific history and culture would be of little benefit to engineering or business students, and said that it should be an elective course rather than a compulsory one. In late March 2025, Parmar introduced a
member's bill seeking to ban universities from offering services based on ethnicity including scholarships, financial assistance, accommodation, housing and designated university facilities. In April 2026, Parmar was the target of a controversial
haka (
Ka Mate) performed by former
Te Pāti Māori President Che Wilson at the Tainui Regional Kapa Haka Competition which included the phrase
"purari karikari iniana" (which has been interpreted as a derogatory reference to
Indians), and mimicked Indian accents and cultural religious practices. In response to media coverage, Parmar described the performance as "deeply troubling" and said that
Indian New Zealanders deserved to be treated with "dignity." She also issued a statement condemning racism as unacceptable irrespective of "who it comes from or who it is directed at." ==Personal life==
