"All up, the Treasury's budget update forecasts show the government's books are expected to remain in good shape over the next four years," ANZ Bank economists say.
"Government spending has been bumped up on both the operational and capital side. This means smaller surpluses and higher debt, but all within, or at, the limits of the government's fiscal targets."
Mike Shirley, a dealer at Kiwibank, says the currency reacted only marginally: "The budget news saw a bit of movement but within a 10-point band."
Investors are still talking about the possibility that China may retaliate to the United States' move to increase tariffs by banning exports of rare earth metals to the US.

"The market has focused on it as a reason to be concerned," Shirley says.
Coming up overnight, New Zealand time, US data, including an update on March quarter GDP and home sales figures, could move the market.
