Members of Auckland's Muslim community are reeling following a string of attacks on their places of worship.

The overnight attacks on mosques at Ponsonby, Mt Roskill, Otahuhu and Ranui saw windows smashed and walls graffittied with the message "R-I-P London".

Javed Khan of the Federation of Islamic Associations says it is clear the vandalism is a backlash to the terror attacks in Britain.

He says the mosque in Otahuhu was hit on Thursday night as well, soon after the London bombings, but police did not come around until the following afternoon.

Javed Khan says the New Zealand Islamic community has already condemned the British attacks as despicable.

Farhaz Rehmen was at the Ponsonby mosque when the attack happened.

Mr Rehmen says he was asleep out the back and he did not even hear it.

He says he is extremely upset about the attacks and he does not understand why people want to take their anger out on the New Zealand Muslim community.

The Prime Minister is disgusted at the attacks

Helen Clark says she is deeply saddened and horrified at what has happened.

She says obviously people are upset at the bombings in London, but it is wrong to target the Muslim community in retaliation.
