Relations between France and New Zealand were strained for two short periods in the 1980s and 1990s over the French nuclear tests at Moruroa and the bombing of the "Rainbow Warrior" in Auckland harbour. The latter was widely regarded as an act of state terrorism against New Zealand's sovereignty and was ordered by then French President François Mitterrand, although he denied any involvement at the time. These events worked to strengthen New Zealand's resolve to retain its anti-nuclear policy. Relations between the two countries are now cordial, with strong trade and many new bilateral links.
