Keith Hayashi, Waipahu High School’s principal who has been serving as interim deputy superintendent since March, has been tapped to lead the public school system as interim superintendent, the Department of Education announced today.

He will oversee the transition month of July. Outgoing Superintendent Kathryn Matayoshi’s term ends June 30 and newly appointed Superintendent Christina Kishimoto begins Aug 1.

“We’re going to continue the good work that’s going on in the department, and work toward ensuring a smooth transition,” Hayashi said.

Replacing Hayashi as interim deputy superintendent will be Amy Kunz, who currently serves as senior assistant superintendent and chief financial officer.

The Board of Education said it planned to name an interim leadership team when it announced Kishimoto’s hiring last month.

“I’m just so excited about them being willing to step up — even above what they’ve already stepped up in the work that they’re leading — to be part of this collaboration to make sure that there isn’t a misstep here in terms of just continuing the work that’s happening,” Kishimoto said at a news conference.

Kishimoto, who was most recently superintendent and chief executive officer for Gilbert Public Schools in Arizona, said she is in town to look for place to live and meet with DOE staff and leadership before her term begins.
