The New Zealand Privacy Commission is to closely watch a lawsuit in the United States against the makers of the iPhone.
Bloomberg reports Apple is accused of allowing applications to send personal information to advertisers without consent.
The suit, lodged in a federal court in California, reportedly relates to both the iPhone and the iPad.
Apple is said in the complaint to claim it does not allow applications to transmit users' data without their permission.
Assistant Privacy Commissioner Katrine Evans says the lawsuit is being watched here with interest.
She says it's not yet clear if the claims affect devices sold in New Zealand.
But she says it could be a breach of New Zealand law if the accusations are proved to be true.
Ms Evans says the Privacy Commission would be interested in looking at the matter further if the claims are upheld.
