It won't be quite the New Zealand birthday experience for one Brazilian woman who is now in prison after being arrested at Auckland Airport.

The 29-year-old was found with 4.6 kilograms of cocaine in her luggage on Sunday.

The woman arrived on a flight from Chile but began her journey in Brazil.

She was questioned by Customs officers and X-rays of her bags indicated the contents needed further investigation. 

The street value of the cocaine she was carrying is as high as $3.2 million in New Zealand.

New Zealand Customs said intelligence provided identified the woman as a high-risk passenger, and suspicions were confirmed after further questioning.

The woman is due to appear at the Manukau District Court on Friday.
