A New Zealand man is in a Thai jail after he was busted in possession of illegal drugs on the holiday island of Phuket.

Taylor Grainger, 41, was arrested with 1.2 grams of ya bah methamphetamine and 0.95 grams of cocaine in Patong.

Phuket police have been conducting a blitz on drugs since December 20.

The arrest follows the recent busts of two other kiwis, both of whom are in prisons in Bali and China where they are facing drugs charges.

Antony de Malmanche, a 52-year-old sickness beneficiary from Wanganui, was arrested at Bali's Denpasar airport and Peter Gardner, 25, was detained in China in November and faces execution by firing squad.
