The Muslim community is worried after a mosque in Tauranga was burgled and two cars were set on fire in the week leading up to one of the biggest religious days of the year.

Traditional men's clothing was stolen from the mosque at the weekend and a car was set alight on Monday evening - another car - a Muslim funeral hearse - was also set on fire outside a Lower Hutt Mosque.

Federation of Islamic Associations of New Zealand spokesperson Dr Anwar Ghani says there's growing concern the stolen clothing could be used to infiltrate the Eid festival this weekend.

The police, including national security, are meeting with the community this evening to create a plan to handle the safety of these events in the lead up to the holy day, he says.
