An ear infection will prevent New Zealand sevens coach Gordon Tietjens travelling with the team when it leaves for the Hong Kong tournament on Sunday.
"I need a little more time to come right so at this stage I am planning to arrive in Hong Kong next Thursday," Tietjens said.
Skills coach Damian Karauna will take over coaching duties and assisted by Tomasi Cama, who is injured and will not play.
"Damian is very experienced in the game of sevens having played for the All Blacks Sevens over eight seasons. He knows the drills and tactics having been with us since late last year so I am sure the team will be well prepared," Tietjens said.
"He will also be supported by Junior [Cama] whose deep knowledge of the game will be a great help to Damian."
