Update: The ʻĀhihi-Kīnaʻu Natural Area Reserve is officially closed again as of 1:19 p.m. on Tuesday, April 10, 2018.  Maui Now has confirmed with state officials that a 10-foot Tiger shark was sighted at 11 a.m. today, and was still seen at 1 p.m.   Mākena lifeguards helped clear the water, and no injuries were reported.  They also confirmed the presence of a shark.  The public is advised that sharks can come and go anytime and people should be aware, and ask questions of ocean safety personnel, parks staff or personnel from the DLNR Division of Conservation and Resources Enforcement.

ʻĀhihi-Kīnaʻu Natural Area Reserve along Maui’s south shore re-opened at 1 p.m. on Monday, April 9, 2018 after being closed since March 28th due to “multiple large sharks” which were seen continuously swimming close to shore, DLNR officials confirmed with Maui Now.  The initial closure was implemented after numerous shark sightings, including tiger sharks.

“Staff and volunteers searched from shore every two hours each day during the closure to determine if the large sharks were still present, but they kept returning to ʻĀhihi Bay during the closed days,” said Dan Dennison, Senior Communications Manager with the Department of Land and Natural Resources.

Carl Meyer of the University of Hawaiʻi reportedly told the DLNR Division of Aquatic  Resources that he thinks tiger sharks are following pupping black tip reef sharks inside the breakers. During a recent count, there were seven blacktop frequenting the shallow waters, but no tiger sharks were spotted.


During the closure, the parking lot for the ʻĀhihi-Kīnaʻu Natural Area Reserve was closed to the public. The road into the reserve was closed for part of last week as Maui Electric conducted upgrades to power lines in the area.

Three years ago, on April 29, 2015, a fatal shark encounter was reported at ʻĀhihi-Kīnaʻu in the area of Kanahena Point.  The incident involved a Kīhei woman who was snorkeling approximately 200 yards from shore in 20-35 feet of water when she sustained fatal injuries from a shark bite.

So far in 2018, there has been only one confirmed shark incident documented by DLNR in all of the Hawaiian Islands. The incident occurred on March 31, 2018 at Kūki‘o Beach in North Kona on Hawai‘i Island when a stand-up paddle boarder was bitten by a 12-foot shark.  The individual sustained severe lacerations to their right forearm and hand, and lost their right leg below knee as a result of the incident, according to information compiled by the DLNR Division of Aquatic Resources.

Study Published on Shark Behavior and Habitat:

The nearly two week closure of the reserve this year comes as a new study was released detailing shark behavior and habitat in Hawaiian waters.


Researchers from the Hawaiʻi Institute of Marine Biology recently published an article in Nature Scientific Reports entitled: Habitat geography around Hawaiʻi’s oceanic islands influences tiger shark (Galeocerdo cuvier) spatial behaviour and shark bite risk at ocean recreation sites.” 

According to the Pacific Islands Ocean Observing System or PacIOOS, the team of researchers used satellite and acoustic tags to track 41 tiger sharks off Maui and Oʻahu “in an attempt to better understand tiger shark movement and habitat use patterns.”  Shark tracks related to the study are available online for public viewing.

Study findings revealed that tiger sharks prefer “insular shelf habitat,” which extends from the shoreline up to a depth of 600 feet.  The report states that:

Overall, our results suggest the extensive insular shelf surrounding Maui supports a fairly resident population of tiger sharks and also attracts visiting tiger sharks from elsewhere in Hawaiʻi. Collectively these natural, habitat-driven spatial patterns may in-part explain why Maui has historically had more shark bites than other Hawaiian Islands.”

The study was prompted by a spike in the number of shark bite incidents off Maui which peaked at eight incidents in 2013, five in 2014, three in 2015, and spiked again to seven incidents in 2016 before dropping to a single documented encounter (in which a snorkeler was “bumped” by a shark) off Maui in 2017.


While there were no shark bites were in 2017, there were some close calls.

The single documented incident occurred on Thursday, Oct. 5, 2017 when a 40-year-old female visitor from Canada was snorkeling about 10 yards off of the point between Kama‘ole II and Kama‘ole III when she was “bumped” by what is described as an 8-foot grey shark. The woman suffered minor abrasions to her left thigh and left arm and declined medical treatment.

Another close encounter occurred on Tuesday, Oct. 3, 2017, at Mākena State Park, when a man and woman spearfishing about 100 yards from shore on the north end of “Big Beach” were approached by an 8- to 10-foot Galapagos shark displaying “aggressive behavior.” The shark circled the freedivers and their dive float, and eventually took their catch of fish. There were no injuries reported, and the beach was closed for two hours.

Another incident was reported on Sept. 21, 2017 after an aggressive shark stole the fish catch of two men spearfishing offshore. The fisherman in that incident said they believed the shark to be a seven-foot Galapagos shark.

For centuries, traditional Hawaiian chants have warned about an increased risk of shark bites in the fall.
