Butler was an obvious choice for Volts bowler of the year and was also named player of the year following consistent performances in all three formats.
He was one of the leading performers in the Plunket Shield with 39 wickets at an average of 25.12, and a key contributor to Otago's success in the twenty/20 tournament with 11 wickets at 25.
Butler played some telling knocks with the bat as well, particularly in the HRV Cup, where his ability to find the boundary proved very useful.
There was no surprise Bates claimed the overall and batting awards for the Sparks, either.
The White Ferns captain had a remarkable summer. She was named the player of the tournament at the Women's World Cup in India and had a brilliant domestic season.
Aaron Redmond picked up the batting prize for the Volts. Last season, the veteran right-hander struggled desperately with his form and was dropped from all three formats.
But he bounced back in a big way, scoring three first-class tons and six 50s, and was the leading scorer in the Plunket Shield with 941 runs at an average of 55.35. Only Glenn Turner has scored more runs for Otago in a season.
Legspinner Emma Campbell claimed the bowling accolade for the Sparks. She took 16 wickets in the one-day competition at 19.31.
Sparks batsman Polly Inglis and Volts seamer Jacob Duffy were named rising stars, while the fielding awards went to Katey Martin and Neil Broom.
Redmond scored the fastest 50 of the season - a 21-ball effort against Canterbury during a twenty/20 fixture at the University Oval.
Volts coach Vaughn Johnson was named coach of the year for his efforts in guiding Otago to glory in the HRV Cup, and Nick Beard's wonderful 188 as a night watchman was singled out as the outstanding performance of the year.
Every year, the association takes the opportunity to acknowledge the efforts of an unsung hero, and long-serving scorer Helen Simpson was named the winner of the outstanding contribution award.
Simpson has been scoring for Albion for 43 years and for Otago on and off for many years, but regularly since the early 1990s.
Otago cricket chief executive Ross Dykes said her length of service was extraordinary and the accolade was long overdue.
''She takes on any task and is just a very quiet and unassuming workhorse in an area of cricket which is often just taken for granted,'' he said.
