The Ministry of Foreign Affairs and Trade is advising those travelling overseas to be more vigilant in the wake of the death of Osama Bin Laden.
A spokesperson for the Ministry says New Zealand is liaising closely with its diplomatic partners and the travel advice is under constant review.
The Australian Government has updated the travel advisory for its citizens, warning people to be more careful about their personal security, especially if they are near mass gatherings or demonstrations.
Meanwhile Britain has told its embassies to review their security for fear of reprisals.
Its Foreign Secretary, William Hague, says there may be parts of al Qaeda that will try to show that they are still in business in the coming weeks.
