The promotion, which was initially set to end on 3 March, will run until 31 March and sees Riviera award a £150 weekly Amazon voucher to the agent that delivers the highest-value booking.
Tom Morgan, the operator’s head of trade, said "an overwhelming number" of agents had entered bookings with Riviera after the incentive was first launched.
“This extension allows us to continue to reward our trade partners for their efforts,” he added. “Trade support is at the heart of everything we do, so we’re delighted to include this incentive alongside our training, fam trips and in-person activities.”
As part of Riviera’s incentive, agents will also automatically be entered into a prize draw to win four 128GB iPad Pros, each worth £899.
