Principals say high-decile Auckland schools can afford more opportunities for their students than schools in the rest of the country.
Annual report figures show the city's decile eight, nine and ten state schools are making as much as 40 percent more per student from non-government sources than similar schools elsewhere.
The primary schools last year received an average of $946 per pupil, including $166 from foreign students and $276 in donations.
Waikato is just a little further south, but the president of its Primary Principals Association, Hamish Fenemor, told RNZ education correspondent, John Gerritsen, many of the region's high-decile schools can only dream of getting so much money from donations.
