A ballot for limited places at the centenary commemorations of Anzac Day at Gallipoli in 2015 opens on Friday.
For safety reasons Turkey has restricted to 10,500 the number who can attend the ceremonies, but an estimated 40,000 from both sides of the Tasman are expected to want to go.
Australia has been allocated 8000 places and 2000 will go to New Zealand. The ratio is based on the relative number of casualties suffered by both countries in the Gallipoli campaign in 1915.
The remaining 500 tickets will be used for people from Turkey, official representatives from other countries and VIPs.
The New Zealand allocation includes special places for direct descendants of Gallipoli veterans, veterans of other conflicts, and young people. The ballot will remain open until 31 January 2014.
Veterans' Affairs New Zealand general manager Rick Ottaway says demand for tickets is very likely to exceed supply.
"By exactly how much, we won't know until we get some feeling for registrations, but it was really the only way that it could be managed, in view of the constraints on the size of the sites at Gallipoli," Mr Ottaway says.
People who win a place in the ballot will still have to pay their own way to Turkey and any associated costs.
Turkish authorities are reportedly considering allowing a flotilla of cruise ships to anchor off Anzac Cove for the commemorations.
Approval would allow an additional 7500 people to witness the events.
Provincial deputy governor Huseyin Kulozu has told journalists that Turkish authorities are considering the flotilla proposal, along with several others, AAP reports, citing News Corp.
