*169 OPINION OF THE COURT BY
This case presents the question whether the police may use a trained narcotics detection dog to sniff all packages in a cargo holding room of a private mail carrier, known to drug enforcement officials as a high volume drug conduit, with the carrier’s permission but without the permission of the senders or addressees. We hold the dog’s sniff was not a search within the purview of the Fourth Amendment or article I, section 7 of the Hawaii constitution. Moreover, we find the police action reasonable because the importаnt government interest in detecting and preventing drug traffic via a known, high volume carrier outweighs the minimal individual interest in freedom from a narcotics dog’s sniff of the packages.
On March 8, 1982, Cаnine Enforcement Officer Jerome Tomaino, a member of the United States Customs Service Drug Enforcement Agency (D.E.A.) Task Force assigned to Honolulu International Airport, brought his dog “Donker” to the Federal Express office at the airport. With the permission of Federal Ex *170 press, Tomaino let Donker run loose in the package holding area. Donker stoрped at a package addressed to Alan Snitkin and scratched it, signaling the possible presence of drugs. None of the humans present smelled contraband.
Based solely оn Donker’s actions, the police obtained a search warrant, opened the package, and found cocaine. They then resealed the package, аllowed Snitkin to pick it up, and arrested him as he drove away.
Tomaino had no reason to suspect any particular package at the Federal Express office сontained drugs. He had brought Donker to make a routine survey of the office as he did every day because, in his words, “Federal Express is known actively for drugs.” According to Tomaino, Fedеral Express is the number one air cargo carrier used by Hawaiian drug traffickers. Of the 179 D.E.A. Task Force narcotics recoveries at the Honolulu International Airport since Octоber, 1979 approximately one-quarter have been made at the Federal Express office.
Federal Express officials cooperate freely with drug enforcemеnt officers. Tomaino testified that he simply calls up to ask when the freight comes in and then brings Donker to the cargo room to sniff the packages.
Tomaino has handled Donker for four years and three months. Initially, both received fifteen weeks of training at the United States Customs Service canine center in Virginia. Donker passed the course and received his narcotics certification. In his career, Donker has correctly sniffed out hidden drugs, including marijuana, heroin, cocaine, and hashish, 325 times. At least 175 of Donker’s strikes have been madе in Hawaii and of those approximately 30 at the Federal Express office at the Honolulu International Airport.
On June 16, 1982, the Oahu grand jury indicted Snitkin on one count of Promoting a Dangerous Drug in the Second Degree in violation of Hawaii Revised Statutes (HRS) § 712-1242(l)(b)(i). On October 5, 1982, Snitkin filed a motion to suppress the cocaine on the ground that Donker’s actions constituted an illеgal search. At the suppression hearing the trial judge granted the motion, citing
State v. Groves,
*171 I.
The first issue raised by the State is whether Snitkin may chаllenge the constitutionality of Donker’s actions. We find this contention without merit.
See, United States v.
Jacobsen, _ U.S ___,
II.
We begin our discussion of the propriety of Donker’s actions with our recent opinion in
State v. Groves,
The novelty of the present case is how Donker’s detection talents were used. In
Groves,
the marijuana found in thе closed suitcase was first smelled by a human, and only then was the dog used to sniff the suspected article.
We disagree. Snitkin’s argument loses sight of our paramоunt holding in
Groves:
a narcotics dog’s sniff of the airspace around a closed container is not a Fourth Amendment or article I, section 7 “search.”
Nevertheless, we do not consider the Fourth Amendment and article I, section 7 to be irrelevant to the police actions reviewed hеre. Although in
Groves
we held a dog sniff is not a search, we also noted that we would not countenance unreasonable or abusive uses of narcotics dogs.
The State interest in detecting and preventing drug traffic via a known conduit is a strong one.
Place,
In contrast, Snitkin’s interest in freedom from a narcotics dog’s sniff of the airspace around his package was minimal. Donker’s sniff of the package holding room posed little threat of harassment, intimidation, or embarrassment to senders or recipients.
See,
*173
Groves,
We conclude the State’s interest in detecting private mail drug traffic via Federal Express clearly outwеighed any sender’s or recipient’s interest in the airspace around his or her package, and therefore the State’s use of Donker to sniff the package holding areа was reasonable. At the same time, however, we emphasize that, absent exigent circumstances, consent, or some other well established warrant exception, a valid search warrant is still required to open private containers identified by a drug detection dog.

Notes
The lack of human confrontation is an important distinguishing factor. While drug detection dogs trained by the United States Customs Service are extremely accurate in detecting contraband concealed in inanimate containers,
