Tietjens calls it quits
The legendary coach, Tietjens, led New Zealand to four Commonwealth Games gold medals, 12 Sevens World Series titles and two World Cup Sevens titles – becoming the most successful coach of all time in the abbreviated form of the game.
He was inducted into the World Rugby Hall of Fame in 2012 and knighted for his contribution to the game 12 months later.
Many great All Blacks have emerged from the teams he has coached including Jonah Lomu, Christian Cullen, Ben Smith and Beauden Barrett.
New Zealand Rugby Chief Executive Steve Tew said Tietjens had carved out a unique place in New Zealand rugby history.
"Titch has guided the All Blacks Sevens team through more than 100 international tournaments, a remarkable achievement that may never be equalled," Tew said.
"The number of former Sevens players who've gone on to become All Blacks speaks for itself and demonstrates the incredible impact that Titch has had on our game.
"To put the length of his career into context, when he first began in this role rugby was an amateur game, Jim Bolger was Prime Minister and several members of the current All Blacks Sevens team hadn't even been born.
"New Zealand Rugby and our country owe him a debt of gratitude for the legacy he's left behind and all the memories and careers he's shaped along the way."
Tietjens said he had taken some time to think about his options following the recent Olympic campaign and felt the time was right for a fresh challenge.
"I love the Sevens game and I'm immensely proud of what I've achieved and what all our players have been able to achieve in my time with the team," he said.
"We were all incredibly disappointed with our results in Rio, but we have to acknowledge just how far Sevens rugby has come.
"It's become intensely competitive and the Olympics proved just how tough it is to win at this level these days.
"I'm sure lessons will be learnt and I wish my successor all the best for the Sevens Series ahead and for the Tokyo Olympic Games.
"I've loved my time in Sevens and I aim to still be involved in some capacity. I'm now working through what those next steps are.
"I'm grateful to New Zealand Rugby for the support they've given me over the years. I want to especially acknowledge the management team and all the players who have contributed to the success of New Zealand Sevens during the last 22 years. I have so many great memories from what's been an amazing time with the team."
The process to recruit a new coach of the All Blacks Sevens team will get underway immediately with Tietjens' successor expected to take the team into the new season which kicks off in Dubai on December 2.
