Prime Minister John Key has paid respects to the 130 victims of the Paris terrorist attacks, laying a wreath with his Australian counterpart Malcolm Turnbull in the French capital.
Mr Key and his wife Bronagh joined Mr Turnbull and his wife Lucy to lay flowers at the Bataclan Theatre, where almost 100 concert goers were gunned down on November 13.
The New Zealand prime minister said both nations were united in their support for France.
"New Zealand and Australia are two countries that are almost the furtherest away from France but at a time of such sadness and heartache for the people of France we've never been closer together," he said.
Mr Turnbull spoke briefly in French.
"We are here offering the people of France, the people of Paris, our most heartfelt condolences and our unflinching solidarity in the face of this terrorism," he told reporters in Paris.
"We are with all people committed to freedom in this battle against terrorism, against violence, against violent extremism."
Details of the tribute were kept secret amid security concerns following violent clashes on Sunday at Place de la Republique, where riot police fired tear gas at hundreds of protesters defying orders to cancel a planned climate change march.
Some of the activists lobbed bottles and shoes during the demonstration ahead of major UN climate talks in the city.
Mr Turnbull and Mr Key flew into Paris on Sunday evening from the Commonwealth Heads of Government Meeting in Malta.
Mr Key will line up alongside around 150 world leaders to outline their positions on curbing global emissions on the first day of the climate change conference on Monday.
New Zealand is taking to the conference a redefined target of a 30 per cent reduction in 2005 greenhouse gas levels by 2030, which it says is a significant increase on the previous target of five per cent below 1990 emission levels by 2020.
Mr Key is scheduled to address the conference on Monday. Because so many leaders are speaking they have split them in to two rooms to the statements through on time.
Mr Key has said the country's new target is credible and he is confident technological developments can curb New Zealand's biggest climate change contributor, agriculture.
It's hoped 196 parties will sign onto a historic deal in Paris to curb emissions and limit global warming to at least two degrees.
