At least 10,000 people are expected for the Ratana 25th Celebrations this year, Ratana Church secretary Piriwiritua Rurawhe says.
Last year's were bigger, because the birthday of the founder of the church, Tahupotiki Wiremu Ratana, fell on a Sunday. January 25 is the focal day for celebrations, and this year it falls on a Wednesday.
Numbers might be smaller but the event is likely to be a bigger than usual this year for politics, because 2017 is an election year. The Ratana celebrations usually start the political year, with the parties taking it in turns to make their pitch to Maori.
This year all the parties will arrive together at 10am on January 24, Mr Rurawhe said. The Maori King, Tuheitia Paki, and paramount Tuwharetoa chief Sir Tumu Te Heuheu will have arrived and been welcomed the day before.
"The chiefs of Maoridom will be sitting on the marae to hear policy for the election."
