Never mind not inviting them back next time, NZ should be looking to cancel their trip this time, before any damage is done.

Muslim clerics accused of hate speech
9:20AM Tuesday February 13, 2007

Two Muslim clerics invited to give speeches in New Zealand have been accused of promoting hate speech in Britain against gays, women and other religions.

Sheikh Khalid Yasin and Islamic scholar Bilal Phillips were last month shown in a documentary on Britain's Channel 4 allegedly inciting hatred at a British mosque.

The Press reported today that Yasin was invited to speak in Christchurch in May 2005 as a guest of the Muslim Association of Canterbury.

Phillips toured the country last year giving lectures as a guest of the Federation of Islamic Associations of New Zealand (Fianz).

Fianz said yesterday it would not invite such clerics in future, while the Canterbury association said Yasin was a kind, tolerant person and would have him back.
