The Ministry of Culture and Heritage is sending seven staff, and Treasury has two officials going. English will open the October 9 party.

New Zealand is spending the cash to be at Frankfurt, despite government policy which encourages development of opportunities mainly with Asia, followed by South America and Russia.
As Minister for Culture and Heritage, Finlayson used $1.8m from the cultural diplomacy international fund for Frankfurt, contrary to the fund's primary target region being North Asia.
A spokesperson for Finlayson said the fund was available for any activities anywhere in the world and not confined to those from the priority region.
"It has been used for the Rugby World Cup and now for Frankfurt. We didn't know about Frankfurt when the priority region was decided."
Tourism New Zealand will use the Book Fair to boost New Zealand's profile in Germany.
"It is not about what happens at the fair but the wider 'buzz' about New Zealand," said spokesman Chris Roberts.
