Carter still had a smile on his face and was backed by a small band of cheering supporters and music.
"I don't know what the hell I've signed myself up for to be honest. It was all good in theory, until I drove to Eden Park tonight realising that I actually had to kick goals for 24 hours," Carter said on his live stream just after 2:30am.
"Hopefully the sun will come up in a few hours and a few friends will come along. It's a pretty dark place at the moment."
Carter has returned to Eden Park to attempt the 24-hour Kickathon as he launches the DC10 Fund - a dedicated fundraising platform in partnership with Unicef Aotearoa New Zealand that will focus on enriching the lives of children in Aotearoa and the Pacific.
The inaugural DC10 fundraising event sees Carter goal-kicking for 24 hours straight, aiming to successfully convert 1598 kicks - the number of test points he scored as an All Black.
Joined by friends and global Unicef supporters Carter has kicked throughout the night with the final whistle to be blown at 7pm on Friday.
Supporters in New Zealand and around the world can show their support for the DC10 Fund by making a donation via the Kickathon website.
Funds raised from the Kickathon will go to the DC10 Fund, directly supporting Unicef's water, sanitation and hygiene programme (WASH) for children in the Pacific, where sanitation-related diseases are one of the leading causes of death for children under five. The partnership will see Unicef deliver water and sanitation to 134,000 children in Kiribati, Solomon Islands and Vanuatu.
"Dan Carter is a role model to so many and he cares deeply about children and young people," said Michelle Sharp, Unicef Aotearoa New Zealand Chief Executive Officer. "We are hugely appreciative of Dan's continued support to highlight the challenges many children and young people face and to amplify Unicef's critical role in supporting children, their communities and their right to thrive."
