The higher spending also indicates the cost of securing the support of NZ First and the Green Party was higher than Labour allowed for in its fiscal plan and some policies were costing more than expected.
Finance Minister Grant Robertson said the Budget should not be compared to Labour's fiscal plan because it was based on Labour Party policy while the Budget reflected the Government arrangement with NZ First and the Greens.
"It is not comparing apples with apples to look at a one party's pre-election document against post-election negotiated arrangements involving three parties. There are differences, that is what political negotiations are about."
He said the Government had stuck to the fiscal responsibility pledge to reduce debt over time and remain in surplus.
The comparison shows spending on welfare and social security was forecast to be $2.2 billion higher than Labour had forecast.
Robertson said that was because of increased costs for its Families Package as well as more people being on benefits, higher housing costs and accommodation subsidies.
Despite increases in the Budget the forecast spending on health was currently $3.35 billion lower than in Labour's plan while education was $3.26 billion lower over the next five years.
Robertson said that shortfall would be made up in the next two years and Labour was likely to spend more than it had planned in those two areas.
"There will be further allocations across the next two Budgets in these areas, and given how much has been allocated already we are likely to exceed the track in the fiscal plan."
Forecast operating allowances in the Budget total $10.3 billion more than Labour's plan, however once the expected future health and education boosts are taken out that goes down to $3.7 billion.
Labour has increased its operating allowance by $24 billion more than National planned, the money coming from an extra $9 billion in debt, higher tax revenue than expected and scrapping National's tax cuts.
National Party leader Simon Bridges said despite its insistence all its policies were costed, Labour had still either had to delay or drop key promises such as extra police and moves to pay schools which dropped donations.
"It shows the fiscal plan had some dodgy numbers in it and that it was false advertising. The voters thought they were getting a credible plan where promises would be kept but actually it doesn't do what it said on the tin."
The fiscal plan was the centre of controversy on the campaign trail after former Finance Minister Steven Joyce claimed there was an $11.7 billion hole in the operational allowance – a pool of money allocated by the government for higher or new ongoing costs.
That was widely discredited after Labour explained that it had moved each year's new allowance to areas such as health or education for subsequent years rather than let it build up in the "operating allowance" line.
However, Joyce and former National leader Sir Bill English insisted Labour's books were too tight and it had not allowed enough for its promises as well as expected increases in Government spending such as wage rises.
