When the erotic novel Fifty Shades of Grey was released, Kiwi bondage and discipline store Khandikane sold out of whips and blindfolds.
The movie will be released two days before Valentine's Day on Saturday, so the online store has stocked up again.
The novel by British author EL James traces the relationship between college graduate Anastasia Steele and wealthy businessman Christian Grey.
Bondage and discipline, dominance and submission feature heavily in the plot.
