HIFK Helsinki and KalPa Kuopio both finished the regular season at the top of the league, tied with 93 points in 36 games.
[22][23] Sauvé had signed in the middle of the 2021–22 season as successor to starting netminder Noora Räty, who left HPK in January to rejoin the KRS Vanke Rays in the ZhHL.
KalPa also bid farewell to a franchise star with the retirement of their captain, the 2020 Player of the Year winner and a three-time All-Star, Tanja Niskanen.
In addition to signing national team players Holopainen and Rantala from Kiekko-Espoo, KalPa attracted Finnish goaltender Aino Laitinen from the Budapest Jégkorong Akadémia of the European Women's Hockey League (EWHL).
In a major loss to the team's offensive production, the linemates both signed in the Swiss Women's League (SWHL A) with EV Bomo Thun for the 2022–23 season.
[24][25] Continuing the pattern of signing at least one French national team player to the roster in each season since 2020, TPS inked defenseman Raphaëlle Grenier.
[26][27] Ilves recruited internationally to fill Keisala's roster spot and brought in Canadian goaltender Camille Scherger from the UPEI Panthers women's ice hockey program of U Sports.
[28][29] Kiekko-Espoo’s Laitinen was not the only Naisten Liiga defenseman to embark on a college ice hockey career in the NCAA Division I, as Krista Parkkonen of HIFK, the 2020 Naisten Liiga Rookie of the Year and a two-time All-Star, joined the Vermont Catamounts women's ice hockey program.
HIFK saw relatively little turnover in comparison to their close neighbors in Espoo, with the departure of just Parkkonen and Czech forward Veronika Lorencová, who left for the EVB Eagles Südtirol of the EWHL and Italian Hockey League Women.
HPK Hämeenlinna improved from seventh place (first in the lower division series) in the 2021–22 regular season to fourth in 2022–23, amassing 67 points.
