All Blacks 7s coach Sir Gordon Tietjens says winning in Hong Kong is always special.

Tietjens says with the history of 7s rugby in the Hong Kong 7s tournamnet, all teams are always gunning for the top prize in So Ko Po.

Tietjens also says that he is still trying out his combinations in the different tournaments ahead of the Olympic Games.

He says they also welcome back Sonny Bill Williams to the side who has been a big boost to the team.

Meanwhile, Fiji play Canada in their first pool match at 12.06pm Friday.

The Hong Kong 7s kicks off this Friday.
