At Christchurch District Court today, defence counsel Kirsten Grey said police wanted another two-week adjournment so they could complete their investigations.
Judge Fred McElrea remanded Greer on existing strict bail conditions until July 22.
Greer was found with a digital camera containing images of the girls, police say, while more cannabis was also allegedly found at his Bryndwr home.
He faces seven charges, including selling and possessing cannabis, Class B controlled drugs morphine, and Ritalin, as well as entering into dealing with two different teenage girls "for the purpose of sexual exploitation" between January and May.
