"If you had asked me back at Christmas time, I wouldn't have even been considering the position I'm in now," said Luatua.
"I was dreaming of one cap, but here I am starting in my fourth game, I'm over the moon, it's a dream come true."
Luatua has impressed in his appearances - playing in a revised flanker role which he is likely to continue for Auckland in the ITM Cup.
"Flanker is my preferred position. I have had a lot of discussions about playing lock and if you put me there I will do the job, but I definitely prefer the flanker position.
Luatua was playing club footy for Auckland University last season and said the transition to Super Rugby has been made easier by the experienced squad members he can learn from.
"In the beginning of the season I was looking up to Jerome Kaino - he's someone I aspire to be like with his physical, go forward style. Right now I'm learning a lot off Ali (Williams) with my lineout jumps. I ask a lot of questions and the boys are always keen to help out - for me it's been great."
The 115kg loose-forward said the key to beating the Chiefs this weekend was to produce a more 'full' performance.
"We need to play for 80 minutes. In the last few games we've had some good phases but we've only played well in patches of 10 or 20 minutes. If we do that I think we can put away some good teams."
The Blues have made six changes to the side that lost 27-20 to the Highlanders last weekend including the reinstatement of All Blacks Ali Williams and Ma'a Nonu to the starting lineup.
Piri Weepu remains on the bench with Michael Hobbs replacing the injured Gareth Anscombe at first five while Rudi Wulf is at fullback, for what will be his 50th game.
Blues: Tony Woodcock, James Parsons, Tevita Mailau, Liaki Moli, Ali Williams, Steven Luatua, Daniel Braid, Luke Braid (c), Alby Mathewson, Michael Hobbs, Rene Ranger, Ma'a Nonu, Francis Saili, Lachie Munro, Rudi Wulf.
Reserves: Tom McCartney, Angus Ta'avao, Filo Paulo, Peter Saili, Piri Weepu, Hadleigh Parkes, David Raikuna.
