Australian Prime Minister Tony Abbott arrived in New Zealand last night for Anzac centenary events and talks on the military mission to Iraq.
It is his second official visit to this country following bilateral talks in February.
The main purpose of his one-day trip is to take part in World War I centenary commemorations, but he will also meet with Prime Minister John Key to discuss terror threats and the two countries' joint military commitment in the Middle East.
Mr Key's office said talks at a working breakfast this morning were likely to touch on the threat of Islamic State and the joint military training mission, the upcoming Gallipoli commemorations in Turkey, the Cricket World Cup and the "single economic market agenda" - the long-term goal to streamline trade between the two countries.
