Judge Stan Thorburn was shown emails between Broxton and the "Book Keeper", who allegedly supplied him with the powders to press into Ecstasy pills. In the emails, the two men discussed price and problems with the strength of the drug mix.
Hundreds of thousands of pills were made, according to police, and large amounts of money were allegedly exchanged between the pair.
The police say Broxton was paid $2 for each pill. They retail for between $40 and $50 each.
Police were concerned Broxton would destroy evidence if he were granted bail and said in court that the pressing machine had not been found.
A week after the first court appearance, Detective Sergeant Bruce Howard confirmed that police were still searching for the equipment.
"We are very interested in talking to anyone who might know where it is," said Mr Howard. Broxton is scheduled to appear again on September 18.
Four of his co-accused, including the "Book Keeper", will appear in the Auckland District Court today to apply for bail and continued name suppression. One is a businessman, known to others in the alleged syndicate as "The Boss".
He and two others, including Brendon Nguyen, were on bail on the same criminal charges laid in Operation Ark last November. More than $20 million worth of assets were seized.
Name suppression has lapsed for one of the men said to have played an important role in the syndicate, a Briton known as "The Banker".
Craig Williams, 46, this week abandoned his bid to be bailed to his apartment in the Metropolis tower.
