The Israeli embassy in New Zealand has been advised to be on alert following attacks on embassy staff in India and Georgia.
Israel has accused Iran of being behind plots to attach bombs to Israeli embassy cars in both countries on Monday.
An Israeli woman was injured when her car exploded in Delhi, but the authorities safely defused a bomb in the Georgian capital Tbilisi.
An embassy spokesperson in Wellington says they have not increased security, but all Israeli embassies have been warned to stay on alert.
Iran has denied any involvement in the attacks.
