A TRIP to the beach was packed with a bit of adventure for Kelly Tranberg and her family.
Kelly, her husband and three kids were at the beach at Five Rocks, when they spotted a bottle.
But this was no ordinary glass bottle, it had a message inside.
"The kids were so excited when we realised it was a message in a bottle," Kelly said.
And the message was from another family who had been on an adventure themselves.
Two postcards were in the bottle from a French family from New Caledonia, who'd been travelling on a catamaran to Auckland.
The postcards, written in French, explain how the French family's 10-year-old son Pablo threw the bottle from the catamaran on February 11, 2013 while they were between Auckland and New Caledonia.
The French family also sent their well wishes to whoever came across their bottle. The postcards even had the family's email address on it, and Kelly has been in touch, hoping to find out more about the family.
"We'll try to keep in touch with the family," Kelly said.
And now her three kids, Tamika, 10, Kylan, 8, and Jazmin, 4, want to throw their own message out to sea.
"The kids have loved it, and are looking at making their own message in a bottle now," Kelly said.
