"It is yet another example of privileging the privileged while everyday New Zealanders suffer," she said.
"The decision to hand out more cash to Wanganui Collegiate is a slap in the face for Christchurch students, parents and teachers who are desperately trying to save the schools that helped them through the traumatic experiences of the last two and a half years."
In June last year Wanganui Collegiate boasted low class sizes in advertisements - after the Government ditched plans to make $43 million savings a year by increasing class sizes.
The school has faced financial strife since 1991 when it made the move to become co-educational and it sold the land and buildings that house St George's preparatory schools, valued at $3.1 million.
Last year there were 518 students over the two schools and this year fees will increase by more than 10 per cent. Outgoing Wanganui Collegiate chairperson Tam Jex-Blake wrote to parents in December last year saying they would have to pay more.
In 2011 then Education Minister Anne Tolley gave Wanganui Collegiate more than $800,000 in extra funding, while the school's application to become a state integrated school was negotiated.
At the time Wanganui Girls' College said there wasn't enough funding in the region to support the current regime of public schools.
