The All Blacks Sevens have suffered a sizeable defeat in their opening match of the Hong Kong Sevens, throwing their tournament into disarray.

Playing against Samoa in the penultimate game of the day, NZ flattered to deceive on the pitch, succumbing to a significant 24-0 defeat.

While tries were hard to come by in the early exchanges, with scores locked up at nil-all until the final moments of first half, Melani Matavao touched down immediately before the break to give Samoa a 5-0 lead going into halftime. 

Samoa scored three further tries through Vaa Apelu Maliko, Paul Scanlan and Steve Onosai in the second half to leave New Zealand with a tough task Sunday.

A pulsating day one is in the books 💪

The All Blacks Sevens will take on pool mates Australia and Hong Kong in Sunday's fixtures and will need to bank two victories in order to give themselves any chance of progressing to the quarterfinals.

After securing first place in the final leg of the 2021-2022 series, missing out on the quarterfinals of the opening tournament of the season would mark a less-than-ideal start to their new campaign.

New Zealand's loss was the only upset of the day, although Spain came ever-so-close to tipping over the United States, with a Malacchi Esdale try in the final play of the game saving the USA's blushes and securing them a 15-14 victory.
