Presiding Judge Purnomo Amin Cahyo said the defendant was proved to have controlled and provided methamphetamine. Harland-White pleaded guilty to all charges.
"The indictment points were met. He was proved as having controlled and stored 29.7 grams of crystal meth," Purnomo said.
Police arrested Harland-White in October 2016 at the Palm Hills housing complex, South Balikpapan, and confiscated 29.7 grams of crystal meth, a digital scale as well as a car, the Jakarta Post reported.
He brought the methamphetamine from Malaysia via sea into Batam and carried it to Balikpapan by plane.
"Before he was arrested, [Harland-White] successfully passed the examination at the airport by tying the drugs to his leg with black duct tape.
A Ministry of Foreign Affairs spokesman told Fairfax it was aware of Harland-White's detention.
"Consular assistance is being provided to him by the New Zealand Embassy in Jakarta."
