• 1500 will be available for all New Zealanders.
• 100 will be reserved for allocation by the Government to special groups such as youth, children of Gallipoli veterans, and others where it is not appropriate to ballot.
New Zealanders who are both direct descendants of Gallipoli veterans and veterans themselves are eligible to enter the ballot in both categories.
Descendants and veterans who are unsuccessful in securing places via those categories will also automatically be entered into the general ballot.
Ballot applicants must be New Zealand citizens or permanent residents aged 18 on April 25, 2015.
Successful applicants will be granted a double pass and can choose anyone to accompany them to Gallipoli.
Veterans' Affairs Minister Michael Woodhouse is expecting there will be strong demand for them.
"One estimate is that we could have four applications for every ticket we've got. So people will need to be in to be part of the ballot but some will be disappointed no doubt," he said.
RSA President Don McIver said even so, Gallipoli is a place to visit any time.
"Whilst there will be people who are disappointed, Gallipoli is always a very special peninsula to visit where you can walk around quietly and contemplate."
Turkish authorities are considering allowing some people to witness the historic event from cruise ships anchored off Anzac Cove.
