The government plans to invest more than $500 million in the Defence Force over the next four years, Defence Minister Jonathan Coleman says.
The investment followed several years of budget cuts which were outlined in a Defence white paper in 2010.
In the Budget next month, government would commit to $100.9m in operation funding for 2014/15 and a total of $535.5m over the next four years.
Dr Coleman said: "It is vital that the NZDF can continue to meet the Government's requirements, whether it is carrying out humanitarian assistance and disaster relief work at home or in the Pacific, or contributing to wider global security efforts."
He said the National-led Government had inherited a long-term funding gap from the previous government.
