A child remains in intensive care after a boat capsized near Taieri Mouth on Saturday, resulting in the death of another minor onboard the vessel.
Authorities are continuing to investigate the boating tragedy, with state maritime safety authority Maritime New Zealand also launching a probe into the incident.
The surviving child remains in the intensive care unit, but is currently in a stable condition, a police spokesperson told Newshub on Sunday.
The boat has also been located.
"Police will continue to make enquiries on behalf of the Coroner and are focused on supporting the family of the people involved in this tragic incident," the spokesperson said.
They also acknowledged several people who came to the aid of the boat's occupants following the capsizing, including surf lifesavers, off-duty doctors and members of the public. The civilians assisted in rescuing those onboard and administered first aid.
"We wish to thank all those people for their assistance and acknowledge the distress they may be feeling."
Local iwi have placed a rāhui in the area of the Taieri Mouth until 9am on Monday.
At around 1pm on Saturday, emergency services were called to Taieri Mouth - a small fishing village situated at the entrance of the Taieri River - after a small boat with an outboard motor flipped while attempting to cross the bar.
Five people were taken to Dunedin Hospital, three of which - two adults and a child - have now been released.
It was confirmed on Sunday morning that one of those hospitalised, a child, had died.
Clutha Mayor Bryan Cadogan said the small village, located about 35 kilometres southwest of Dunedin, sees a surge of activity around public holidays.
"There are a lot of people there for Easter. It's a really popular boating area," he told Newshub.
Addressing Saturday's tragedy, Cadogan noted that water is unpredictable and boaties should always remain vigilant.
"Anything can happen... you've always got to be on your mettle," he said.
"River mouths and bar crossings are particularly dangerous activities because of the number of currents that are present."
Cadogan said visitors should always seek advice from locals before heading out on the water.
"We would just advise to check with a local and get that local knowledge about the local risks."
The police spokesperson told Newshub that anyone involved in the incident should consider reaching out for support.
"If anyone feels they need support following this incident, Police encourages them to reach out for help. Free call or text 1737 any time."
