New safety measures will be put in place between Mauao and Matakana Island prompted by the increase of harbour users.
Bay of Plenty Regional Council's maritime team is trialling the installation of new yellow 5 knot buoys at the Tauranga Harbour entrance.
The purpose of the buoys is to clearly mark where any vessels travelling through the harbour channel should be slowing down to 5 knots if travelling outside the marked shipping channel and close to shore.
Deputy Harbourmaster Daniel Rapson said they saw a huge increase in boats and jet skis on the water last summer and were predicting the same if not more this year.
"As well as more boats and jet skis, there has been a rise in popularity of paddle craft such as waka ama, stand up paddle boarding and kayaks using the entrance or travelling around Mauao.
