Crooks powered on to the masters 1 podium with a bronze in the individual pursuit and silver in the points race.
The points race was exciting, as South Canterbury's Reon Park lapped the field three times and Crooks once.
Crooks was delighted with his results and attributed his improved performances to consistent high-intensity training and more time on the track.
Lachie McGregor was an impressive fifth in the under-19 men's omnium, his first year in the age-group.
His best result was third in the individual pursuit.
The team sprint trio of Stu Thomas, Gordon Westoby and Chris Henderson struck the Southland 1 team in the ride for bronze and was beaten by just under 1sec.
Westoby also rode well in the final stages of the scratch race and finished a close fifth while Stu Thomas progressed to the final of the keirin.
Novice Ewan Sime impressed in the under-15 boys category, placing sixth in the 500m time trial and progressing to the semifinals of the 750m derby race.
Rachel Sime was pipped by less than a second in the ride-off for masters 1 bronze in the individual pursuit and Glenda Bruce performed the same feat in masters 2 women.
This week, the elite track championships start in Cambridge at the new Avantidrome.
Leader of the elite road series Elyse Fraser will be one to watch in the elite women's events along with New Zealand sprint team member Katie Schofield.
Brad Evans and Patrick Jones, who are both under the radar, may cause upsets in the men's events.
Newcomer Bailey Saville (17) is a strong medal contender in the timed events.
She, along with the talented Lachie McGregor, will be looking for selection to a New Zealand development group.
