Primary elections All Progressives Congress On 20 April 2022, the APC National Executive Committee announced the party's schedule for senatorial primaries, setting its expression of interest form price at ₦3 million and nomination form price at ₦17 million with a 50% discount for candidates younger than 40 while women and candidates with disabilities get free nomination forms. Forms were to be sold from 26 April to 6 May until the deadline was later extended to 10 May then 12 May. After the submission of nomination forms by 13 May, candidates were screened by a party committee on 14 and 15 May while 18 May was the date for the screening appeal process. Ward congresses and LGA congresses were set for 16 and 17 May to elect delegates for the primary. Candidates approved by the screening process advanced to a primary set for 27 May, in concurrence with other APC senatorial primaries; challenges to the result could be made on 28 May. On the date of the primary, the primary committee chairman noted discrepancies in the delegate lists before postponing the vote until the next day; earlier on 27 May, a candidate—former Senator
Nkechi Nwogu—withdrew over the state party's internal crisis. On 28 May,
Samuel Onuigbo—
House of Representatives member for Umuahia North/Umuahia South/Ikwuano—won the primary, defeating former Commissioner for Industry Henry Ikoh by a 2% margin. However, in the weeks after the primary, a plan to substitute in
Emeka Atuma as the nominee was concocted by some state APC leadership members; the plan went into motion in June when a 7 June rerun primary was won by Atuma and the APC submitted its list of senatorial nominees to INEC with Atuma instead of Onuigbo. In response, Onuigbo sued before a High Court in
Abuja to stop the substitution plot. Although the court dismissed Onuigbo's lawsuit in October, his appeal was successful as a late December Court of Appeal judgment ordered INEC to recognize him as the APC nominee. As both politicians awaited the Supreme Court ruling in late January, some elements of the Abia APC (including the Tinubu/Shettima Campaign Organisation) continued to label Atuma as the Central senatorial nominee. However, the apex court upheld the Court of Appeal judgment and maintained Onuigbo as the valid nominee.
All Progressives Grand Alliance On 25 March 2022, the national APGA announced its senatorial primary schedule, setting its expression of interest form price at ₦2.5 million and the nomination form price at ₦7.5 million with a 50% discount for women candidates and candidates with disabilities. Forms were to be sold from 29 March to 11 April but the deadline was extended to 15 April; after the submission of forms, senatorial candidates were screened by a party committee on 20 and 21 April while the screening appeal process was held on 3 May. Ward congresses were set for 10 May to elect delegates for the primary. Candidates approved by the screening process advanced to a primary set for 28 May, in concurrence with all other APGA senatorial primaries; challenges to the result could be made on 30 May. In the primary,
Ahamdi Emmanuel Nweke—the APGA senatorial nominee in 2015 and 2019—was the sole candidate in the primary and won unopposed.
People's Democratic Party On 16 March 2022, the national PDP announced its senatorial primary timetable, setting its expression of interest form price at ₦1 million and the nomination form price at ₦20 million with a 50% discount for candidates between 25 and 30. Forms were to be sold until 1 April but the party later extended the deadline four times before reaching a final deadline of 22 April. After the submission of nomination forms by 25 April, candidates were screened by a party committee on 27 April while 2 May was the rescheduled date for the screening appeal process. Ward congresses were set for 29 April and LGA congresses were rescheduled for 10 May to elect delegates for the primary. Candidates approved by the screening process advanced to a primary set for 23 May, in concurrence with other PDP senatorial primaries but due to often violently enforced Monday stay-at-home orders by separatists, southeastern state parties held their primaries on 24 May; challenges to the result could be made on 25 May. On the primary date, the screened candidates contested an indirect primary that ended in Austin Akobundu's victory. Akobundu, the former Minister of State for Defense, won with nearly 99% of the votes cast and electoral officer Amah Abraham labeled the primary as free, fair, and peaceful.
