Tietjens said: "DJ, Lote and Tomasi have played in over 40 tournaments and there are quite a few players in this squad that travelled to every tournament in the Series last year which gives them invaluable experience to pass down to the younger players.
"There are some young players in this squad showing great promise which bodes well for the future as we head towards the 2016 Olympics,'' he said.
The New Zealand sevens team will be holding a public training session at Porirua Park this Saturday at 10am.
