Surf casters who usually enjoy fishing at the mouth of the Kaituna River will need to find a new, temporary spot after this weekend.
Road access to Te Tumu Cut, also known as the Kaituna Cut, will close for six months.
The Ford Rd access to the Cut and Maketū Spit will closed from August 1 until December 20, to enable construction work that will restore 600,000 cubic metres of freshwater flows into Te Awa o Ngātoroirangi Maketū Estuary on every tidal cycle.
Bay of Plenty Regional Council Kaituna catchments manager Pim de Monchy said the council knew the area was popular with people fishing "and we're really sorry for the inconvenience".
"But this project will benefit them in the long run with improved facilities, estuary health, and kaimoana (fish and shellfish) habitat."
