it's not the southern cross, but the UK Flag because New Zealand was first colonised by the British.

The Southern Cross on the New Zealand flag represents NZ's location in the South Pacific Ocean (the blue background).
At the moment the southern cross is an indication of Australian pride, with many choosing to tattoo themselves and attatch southern cross stickers to vehicles. I have a southern cross tattoo as I am about to serve in the military and feel a stong sence of national pride. The soutrhern cross can mean different things to different people. Cheers
The Southern Cross stars also known as the 'Crux' is not just special for Australia and New Zealand, but also special to most if not all countries in the Southern Hemisphere.
You can find the Southern Cross stars on the flags of countries such as Australia, New Zealand, Papua New Guinea, Samoa and Brazil.
A number of government, provincial and company flags in the sothern hemisphere can also be found sporting the Southern cross. The Argentinian province of Tierra del Fuego has a very prominant Southern Cross on their flag for example.
As the Southern Cross is visible mostly only in the southern hemisphere, it has therefore become a symbol of the southern location of its users.
The Southern Cross stars where also at one time very important to early sailor in the southern hemisphere for navigation and is most likely one of the main reasons it became so important to people in the southern hemisphere.
The Stars on the New Zealand flag represent the Southern Cross Star constellation which is only visible in the Southern Hemisphere, and south of latitude 30 degrees in the Northern hemisphere. The formation actually omits the fifth star in the constellation.
The New Zealand flag has a dark blue background. It has the Union Jack in the upper left-hand quadrant and to the right are four red stars, outlined in white, each with five points. The stars are shaped like the Southern Cross, which is a star constellation visible from New Zealand.Unlike Australia's flag, the NZ flag omits the smallest star from the Southern cross, and the stars are red with a white border rather than all white. There is also no Commonwealth star on the NZ flag.See the related link below for an image.Description:at the top left it has the British Flag taking up one quarter of the flag, and then on the right, there is the Southern Cross, four white stars in a white Diamond Shape.The Background is a Dark Blue.
The union jack in the top left is the British ensign included when NZ was still a Briish colony. The four red stars represent the 4 brightest stars in the southern cross as seen from New Zealand.The blue represents the pacific The Stars represent the southern cross The union jack represents the commonwealth, british emprie and the Queen (God Save Her Majesty) The blue represents the pacific The Stars represent the southern cross The union jack represents the commonwealth, british emprie and the Queen (God Save Her Majesty)
Quite simple (1) The NZ flag does not have the "Commonwealth Star" which is an integral part of the Australian flag (this is the six pointed star to represent the six founding states plus Australia's territories, located under the Union Jack) (2) The NZ flag has the Southern Cross coloured red with white borders(rather than white on the Aussie flag) (3) The Southern Cross on the NZ flag only has four five-pointed stars (rather than five on the Aussie - four with seven points and one with five) (Typo on original answer incorrectly said the stars on the Aussie flag were blue - they are of course white

The four stars symbolises the constellation 'the Southern Cross', represent the stars Alpha, Beta, Gamma and Delta. The Southern Cross is a prominent constellation in the southern hemisphere, and represents New Zealand's geographical position to the rest of the world.
In the top left corner is a representation of the Union Flag, which is a composite of the flags of St George, St Patrick, and St Andrew, which each are crosses.The fourth cross on the flag is the Southern Cross, of the constellation CRUX.In the NZ flag, the stars of the Southern Cross are each "red stars with a white background".
Australia and New Zealand both have a dark blue flag with a Union Jack in the corner. Te Australian flag also shows the Southern Cross as 5 white stars and the NZ flag the Southern Cross as four red stars

The union jack is to show our connection with great Britain. The 4 red and white stars are for the southern cross. The background of blue is for the pacific ocean that surrounds New Zealand
