Charles, who is New Zealand's first major champion having won the Open Championship in 1963, claimed 76 professional wins in his career - including six victories on the PGA Tour.
He earned seven top-five finishes at majors, 11 top-10s, and made the cut 44 times.
The 100th edition of the tournament begins at Milbrook resort and The Hills on Thursday.
SIR BOB CHARLES has just made a HOLE IN ONE on the very last hole of the par three course during the Champions Day!
What a way to ignite the 100th NZ Open and show off the new Farm Course to the world.
