Security has been boosted around Jewish places of worship and gatherings following last night's deadly attack at Bondi Beach.

Two gunmen opened fire on a crowd of about a thousand people celebrating the first day of Hanukkah, killing 15 and injuring 40.

Holocaust Centre of New Zealand Chair Deborah Hart says New Zealand's Jewish community is 'reeling' following the attack, and tributes are flooding in. 

"We hold those directly affected in our hearts, but we know that we have to be resilient and we have to go on. And we've only had the first night of Hanukkah, and Hanukkah is the festival that has carried us through centuries of persecution."
