He was promoted with them from the second division to the NBL and then joined the Auckland Stars in 1994. In eight seasons with Auckland, he won five NBL titles (1995, 1996, 1997, 1999 and 2000), and was named NBL Coach of the Year three times (1995, 97 and 99).
He remains the most victorious coach in the history of the New Zealand NBL. Baldwin's involvement with the Stars continued after he left as coach; he owned the team when they were eject from the NBL due to financial problems.
In 2001, he took the reins of the New Zealand national team. By winning the 2001 FIBA Oceania championship, the Tall Blacks — as New Zealand are known — qualified for the 2002 FIBA World Championship, and even reached the semi-finals; this is the best performance by an Oceania team in the history of the World Championships. Baldwin was made an Honorary Officer of the New Zealand Order of Merit in the New Year Honours 2003, for services to basketball. For his achievements as coach of the New Zealand team, Baldwin was awarded the coach of the year at the Halberg awards — New Zealand's premier sports awards — for both 2001 and 2002.
In June 2011, Baldwin was hired to coach the Jordan national basketball team.
