Alaimalo is an Auckland-born outside back, who grew up playing youth rugby for Canterbury. In 2016 he represented Northland in the Mitre 10 Cup, where he showed off his skills and caught the attention of the Chiefs.
He made 8 appearances for the Chiefs during the 2017 Super Rugby season scoring 2 tries in his debut season. He also started in the Chiefs historic match against the British and Irish Lions.
His fine start in the Chiefs jersey earned him the Rookie of the Year Award.
Alaimalo took his Super Rugby form into the 2017 Mitre 10 Cup helping his side to a Championship semifinal. He played every single minute for the Taniwha in 2017 and ranked in the top five of the competition in four categories: carries (116), defenders beaten (44), metres (827) and offloads (21).
He was once again named in the Chiefs Super Rugby squad for the 2018 season before signing for the Tasman Mako for the 2018 season. Alaimalo played all 21 games he could possibly play for Northland during his time there.
Alaimalo is expected to have an extended run with the Chiefs during the 2018 Super Rugby season as he has been tipped as James Lowe's replacement.
In February 2018 Alaimalo signed new 3-year-deal with the Chiefs.
