Finance Minister Bill English says the focus on helping business to be competitive is starting to have some impact.
The Government is expecting to be back to surplus by 2014-15 after new figures showed a steady improvement in its financial position.
In the nine months to the end of March, its tax take was $535 million higher than it forecast in December.
Opposition parties say the Government should be concentrating on creating jobs, but Mr English told Radio New Zealand's Morning Report programme that, over time, business confidence is what will open up jobs.
"We do everything we can to support the people who create the jobs, because in the end someone gets employed when a business decides to sign up another person backed by the sales of their products and the investmen of capital."
