Similarly, here in New Zealand any flights with less than 90 seats do not require security screening. On some routes, our airline flies turboprops (ATR 72) and jets (A320) on the same route depending on the demand / time of day. As it's a short flight (~1 hr), the flight-time is similar with either option but by booking on the ATR you can avoid security screening entirely. Paired with generally small airports, this means I can arrive at the airport 20-30 mins before departure.
