UNITY is the theoretical political journal of Socialist Worker (Aotearoa), published quarterly in Auckland, New Zealand, since December 2005. It is edited by Daphne Lawless, and each issue focuses on a central theme of interest to the socialist and radical left movement.

The first edition of Unity, published in December 2005, explored the issue of Left regroupment both in New Zealand and internationally. The second edition (March 2006) looked at the history of the Labour Party, contending that traditional Social Democracy had now morphed into Social Liberalism.

The third edition (published in June 2006) looked at radical union movements and was entitled "Strike! The Workers Weapon", investigating key flashpoints between the labour movement and capital in New Zealand in 1913, 1951 and more recent times. A fourth copy (September 2006) developed a positive analysis of the Venezuelan Revolution, contending that Latin America was now a continent in revolt, leading the way to a Socialism of the 21st Century.

The fifth edition, published in December 2006, explored the possible impact of Climate Change on the world, its central thesis arguing that capitalism itself was the motor of Global Warming. The sixth edition, entitled "Cracks in the Empire" (May 2007), examined Anti-Imperialism in the Middle East, Latin America and elsewhere.

UNITY has a print run of just over 1000 each edition, and is widely read on the NZ Left. Notable left wing and socialist contributors to it include John Minto, Chris Trotter, George Monbiot, Dean Parker, John Molyneux, Alex Callinicos, John Bellamy Foster, Sue Bradford, as well as Marxist writers from groups such as Socialist Worker, the Democratic Socialist Perspective and the International Socialist Tendency.

It is not available on the internet as yet.

Unity has been a common name for left-wing newspapers, and was the title of a newspaper published in New Zealand from 1980-1990 by the Workers' Communist League.
