Boy's death in Marlborough Sounds in 2015 caused by 'unknown' allergen
At 7.30pm on January 16, 2015, Mano Louis Aday Simond was a 13-year-old boy excited about exploring an abandoned hotel in the Marlborough Sounds.
Less than two hours later, the otherwise healthy young boy was dead.
Mano, born to French parents in the Canaria Islands, died of anaphylactic shock caused by an unknown allergen, coroner Carla na Nagara has ruled.
On the day he died, Mano – who had a history of asthma, which contributed to his death – had explored a shipwreck in St Omer Bay and collected cockles from the shore with his father, Patrick Simond, while their yacht was moored 200 metres from shore.
He did not eat any raw shellfish but had a lunch of chicken curry, carrots, broccoli and rice.
Later in the day, he picked wild flowers for his mother and played soccer and football with his brothers, Maxime and Jonathan.
Back aboard their yacht his mother, Viviane Deschamps, baked apple muffins with "Rhum Arrange" – flavoured rum.
Shortly after 7.30pm, Mano and his brothers and father returned to the boat, behaving "like his usual self".
He and his brothers had a muffin each and, within 10 minutes, Maxime was complaining of an itchy throat but felt better after drinking water.
Mano then went to wash his hands but told his mother he was having an asthma attack.
After a puff from his inhaler, his symptoms worsened and his mother administered it further.
Realising how severe the situation was, Deschamps radioed for help.
A doctor holidaying nearby happened to hear Deschamps' plea for help over his marine radio.
The doctor set out with his inflatable boat to help.
In the meantime, Mano's father took his son ashore on a dinghy to seek help from a nearby house.
When they arrived about 8.15pm, the residents called emergency services and Mano was described as having a blue face and lips, with shallow and laboured breath, the report said.
His brother and mother arrived with ventolin but could not administer it so commenced CPR.
Mano's breathing continued to decline and his mother said "there was no more space between breaths".
Foam and vomit came out but CPR continued before Gilchrist arrived and assessed Mano, who was showing no signs of life.
Gilchrist continued mouth-to-mouth until a helicopter arrived and staff assisted and administered adrenaline.
CPR was ceased about 9.15pm and Mano was declared dead, the report said.
The coroner noted Mano had been diagnosed with asthma at the age of 5 and had attacks about once or twice a year.
Ba Nagara's findings stated: "There was no indication that Mano was allergic to any food or foreign substances and was otherwise a very healthy boy."
A post-mortem determined the cause of death was fatal anaphylaxis with cardiovascular shock as a mode of death, however, the exact cause of anaphylaxis could not be identified, the report said.
Na Nagara concluded the report stating that she did "not consider it necessary to make any comments or recommendations".
