Kearney, 35, suffered a high-grade hamstring tear against Richmond back on September 29.
She has missed six games, including falling short of playing in North's qualifying final win over Adelaide just under a fortnight ago.
But after passing a fitness test on Wednesday, the aggressive, pacy and skilful half-back has been cleared to face the Power at Ikon Park on Saturday.
The eight-time All-Australian will provide crucial leadership and drive out of defence.
"Emma will play this weekend after training well on Wednesday morning," North Melbourne women's football boss Erin Lorenzini said.
"It is a credit to her dedication to the team, with Emma doing everything in her power to return during finals whilst continuing to support the team as much as she could from the sidelines.
"We look forward to having her experience and leadership back out there in such an important game."
