Representatives from every kohanga reo throughout the country will be at a hui aimed at making changes to the leadership of the movement.
The hui starts at midday on Friday and runs until Sunday.
The gathering has been called by the Maori King before, but was arranged before an independent report cleared the Kohanga Reo National Trust of financial mismanagement allegations.
However, claims of mis-spending by its subsidiary, Te Pataka Ohanga, remain.
Chair Tukoroirangi Morgan is expecting about 1200 people to attend from more than 400 pre-schools. He says there will be representatives from all of the kohanga.
Mr Morgan says most of the hui will be dedicated to changes in the movement, and all the board members will be present. He says several options will be discussed, but won't say what they are.
Mr Morgan says people attending would be presented with a lot of information, with the focus on reaching some resolutions before the end of the hui on Sunday.
Some kohanga reo say the hui must ensure the trust gets back on track and focusses on the education of tamariki.
Ruka Broughton who is the Aotea district kohanga reo manager in Whanganui says the hui is a long time coming and among other things he wants to see change.
"It is also imperative that whanau and their voice are heard, so the hui at Turangawaewae marae will be a time to hear what the people want to contribute - their views, their ideas, their aspirations."
But Whaea Rangi who is a head kaiako (teacher) at a Nelson kohanga reo, Kia Tau te Rangimarie, says the hui is a chance to look to the future.
She says it's hoped the hui will get things back to normality so the kohanga can be run in the best way possible.
Last month, the Kohanga Reo Trust said it would fast-track efforts to set out the direction and structure needed to move forward, including the make-up and membership of the board, with help from kohanga whanau at the national hui.
