Ardern said the extra money for early intervention was only "one of the components of the package" of extra learning support initiatives in the Budget.
"Next week's Budget contains a major funding boost for a significant package of learning support initiatives," she said.
Martin and Education Minister Chris Hipkins are due to take a longer-term "action plan" for learning support to the Cabinet in October.
Rotorua Girls' High School Year 13 student Georgia Brouwer cried when she met the Prime Minister at today's education summit.
"As soon as I saw her a wave of emotion came over me. I didn't know what to do so I just cried," she said.
"I think she's such an inspiration for our people with all she has done so far. She appears in our communities and interacts with people in ways you would never see a typical prime minister do."
She managed to tell Ardern that she attended Rotorua Girls.
"She said she had many friends who used to go there when she was living in Murupara," Georgia said.
"I just said, 'Thank you for being an inspiration to us all', basically told her that I love her.
"She said, 'Thank you very much'."
