Lawrence's favourite memory was during his first trip with the team. Tietjens turned 50 in South Africa and the team decided to perform a haka at his birthday dinner.
"We were waiting for a tear from this hard man, but it never came."
Another Tauranga ex-sevens international Peter Woods had reason to be hugely grateful for the sheer cheek of Tietjens.
Tietjens had just won selection as the national sevens coach in 1994 and had his eye firmly on three Bay young guns, Woods, Joe Tauiwi and Martin Jones.
In those days the All Black selectors had a big say in who made the sevens squad and their list omitted the three Bay boys. Undeterred, Tietjens simply switched his list for the All Black selectors' list and that became the names read out to the nation.
He wanted players that played his style rather than 15-aside players who tried to play sevens. Tietjens was bailed up afterwards by All Blacks selector Laurie Mains for switching the lists and his international coaching career could have had a different ending if he had not picked a winning team.
"The rest is history," Woods said.
Woods coaches Rangiuru's division one team and Lawrence is still scoring tries for Mount Maunganui.
