Playing career
Warriors
Guttenbeil was set to star for Manly but his decision to sign with the yet to be formed Super League competition saw him out of favour with the club and so he returned to New Zealand to play for the Auckland Warriors in 1996.

He also switched his international allegiance to New Zealand and was in line to play for the Kiwis in 1996 but injury ruled him out of his Kiwis début that year.

Guttenbeil played at second-row forward in the Warriors' 2002 NRL Grand Final loss to the Sydney Roosters. He went on to become one of the longest serving Warriors, playing eleven seasons with the club and became the second player to ever receive a testimonial from the club, the first being Stacey Jones. Guttenbeil was also the only player in the club's history to have a playing jersey designed for him. He went on to play in ten Test matches for the Kiwis, playing his last in 2005.
