The Southland duo dominated the masters women's 45-49 year age-group category at the event in Auckland.
Criglington picked up six gold medals with victories in the individual pursuit, 500m time trial, 10km points race, sprint and 5km scratch race.
Nicola Stevens picked up five silver medals at the 2017 World Masters Games.
She also paired up with Carolien van Herrikhuyzen from the Netherlands, a rider she has previously raced with at the UCI Masters Track Cycling World Championships.
Not to be outdone, Southland's Nicola Stevens challenged Criglington in every event.
She won five silver medals in the same age group and picked up a fourth in the team sprint with Karen Forman from Australia.
"Nic pushed me all of the way," Criglington said.
"Racing was hard and fast and I was absolutely thrilled to come away with the results."
"Going into the event I was a bit unsure how my form was after racing at the nationals in mid-March, so I was pleased that my times for the individual pursuit and 500m time trial were only fractions of a second slower that what I had done at the nationals."
Criglington enjoyed riding in good sized fields with riders from New Zealand, Australia and the US, while other age groups also had riders from France, the Netherlands, Australia, New Zealand and Great Britain.
Meanwhile, three southern rowing clubs were represented at the week-long World Masters Games regatta on Lake Karapiro.
Wakatipu Rowing Club's longest-standing members, Hans and Dorothy (Dot) Arnestedt have been rowing with and alongside Riverton Rowing Club and Awarua Boating Club representatives.
Awarua Rowing Club's Rex Ryan was best medalled with golds in the men's 'H' age-group single and double, the latter won with Riverton Rowing Club's John Wilson.
The two also scored a silver in the coxless H pair. H category crews are 70+ years of age.
Composite women's G coxed four Ann Hopcroft, Dot Arnestedt, Jocelyn Dobson, Jessie Blakie and coxswain Faye Brinsdon were the first southern medal winners, grabbing a bronze.
Riverton made the podium again through Wilson and Dobson in the mixed F-G double, with the second fastest time across the three G (average 65+ years) divisions.
The rowing event of the World Masters Games included 160 events, with 1970 entries and more than 1150 competitors.
