The Organisation for Economic Co-operation and Development says New Zealand directed 21.2% of its public spending to education in 2009.
That was enough to push it past the previous biggest spender, Mexico, by nearly one percentage point.
The OECD average is 13%.
The report also considers public spending on education as a proportion of gross domestic product.
Again, New Zealand ranks highly, with its figure of 7.2% exceeded only by Sweden, Norway, Denmark and Iceland.
