Kiwis call reinforcements, but no Sonny Bill
However, the name of high-profile code-hopper Sonny Bill Williams not on the list.
Tietjens believes Williams is not ready for Sevens yet.
Tietjens' team suffered a rash of injuries at the Dubai Sevens at the weekend.
Five players are returning home after sustaining injuries in that tournament.
They are Scott Curry (dislocated shoulder), Gillies Kaka (ankle), Tim Mikkelson (concussion), Sherwin Stowers (broken arm) and Regan Ware (ankle).
They have been replaced by All Black Sevens squad members Antonio Kirikiri (Manawatu) and Beaudein Waka (Taranaki).
Waaka has recovered from a knee injury sustained in Dubai last week after passing a fitness test.
They are also joined by Ambrose Curtis (Manawatu) who played for the team last season.
Despite the massive injury crisis, Tietjens was not prepared to rush his superstar, Williams, into the frontline in Cape Town – where, ironically, Williams and New Zealand have a massive following.
Williams flew with the New Zealand squad to the United Arab Emirates for the inaugural round of the World Series and featured in a non-playing capacity after he was named in Tietjens' core squad to prepare for the Olympic Games in Rio next year.
"He's never played Sevens," Tietjens said, when asked by the 30-year-old All Black centre was still left on the sidelines.
"I jokingly said to him that he might get to play earlier than we first thought. He said ‘can I do that?'. We've got a tournament in South Africa in five days' time and the bodies have taken a hammering.
"We've got a plan for him and we'll stick to that. He'll come in really conditioned to play sevens and train with us and then, when it's time to get him out, we will.
"That applies to so many others too. Wellington or Sydney they'll come in because we'll need them."
