Winston Peters demands Australia changes its flag

Winston Peters has upped the ante in the war of words with Australia, accusing our trans-Tasman neighbours of copying the New Zealand flag and demanding they change theirs.

The acting prime minister told TVNZ that Australia should change the flag they've been using for more than six decades.

Peters caused the stir on morning television when questioned about the consistency of his views.

The New Zealand flag was adopted on March 24, 1902, followed by Australia's adoption on April 14, 1954 - more than 50 years later.

"We had a flag that we've had for a long time, copied by Australia, and they should actually change their flag and honour the fact that we got there first with this design, being decided by a Prime Minister and his legacy," Peters told TVNZ.

The two flags are often confused due to their similarity.

The comment comes after Peters previously criticised Australia for deporting New Zealand nationals without trial.

"When you're in a foreign country you're expected to obey their laws," he said.

"But someone should be tried before they're evicted from a country."

Last week, Peters and Justice Minister Andrew Little appeared on the ABC's Foreign Correspondent programme critical of Australia's deportation policies, saying there appeared to be a "venal, political strain" to them and "certainly not consistent with any humanitarian ideals that I thought both countries once shared".

More than one thousand New Zealanders have had their visas cancelled in Australia since stricter deportation laws were introduced four years ago.

In the same period, New Zealand has sent back only nine Australian citizens.

Australian Home Affairs Minister Peter Dutton said New Zealand needed to keep in mind the country was a buffer between themselves and boats.

"(New Zealand) don't contribute really anything to the defence effort," Dutton said last week.

"There's a lot that we do for New Zealand."
