Anzac Day 100th commemorations at Gallipoli in 2015 will be limited to 2000 New Zealanders, and 8000 Australians.
Veterans' Affairs Minister Nathan Guy launched a public consultation programme on Wednesday on how to ballot attendance.
"April 25th 2015 will mark the 100th anniversary of the Anzac landings on the Gallipoli peninsula in Turkey. Because of the historical significance, we expect many more people than usual will want to attend commemorations," he says.
Mr Guy says the Anzac Commemorative Site in Gallipoli has a limited capacity, which means New Zealand and Australia will need to manage numbers in 2015 to ensure everyone's safety.
"The ratio of New Zealand to Australian places will reflect each country's casualties at Gallipoli in 1915," says Mr Guy.
The Australian Government also launched a consultation programme on Wednesday.
Australian Veterans Affairs Minister Warren Snowdon expects there will be high public demand to attend the Gallipoli Dawn Service,
After hearing from the public the New Zealand Government will make a decision in early 2013 on the balloting principles.
The survey and more information can be found at www.gallipoli2015.govt.nz, with submissions due by 25 November.
