The Ministry for Primary Industries says the new album by popstar Katy Perry album may pose a biosecurity risk.
The chart topping album Prism contains flower seeds for the Swan River Daisy which fans are encouraged to plant.
The ministry says all CDs on sale in New Zealand have met the import requirements but it's worried about some being purchased online from other parts of the world.
It says it will closely monitor the International Mail Centre to try and pick up any imported albums.
The ministry has been in discussion with the New Zealand distributor about the additional seeds.
Meanwhile, the BBC is reporting that bio-security officers in Australia are also concerned about the free seeds.
