Auckland needs Pakiri’s sand, commissioners hear Kaipara Ltd legal representative Morgan Slyfield. Commissioner chair Les Simmons. A new map produced by Kaipara Ltd sections off an area to be avoided by dredging, marked in grey. Hearings for Kaipara Ltd’s resource consent application to dredge two million cubic metres of sand offshore from Mangawhai and Pakiri began this morning. Just weeks ago, it was revealed by the Mangawhai Harbour Restoration Society and Friends of Pakiri group that Auckland Council’s consent compliance monitoring team was investigating Kaipara Ltd due to alleged environmental damage. Mangawhai Harbour Restoration Society chair Ken Rayward says the society organised a team of divers who reported that an 18km trench had been caused by continual dredging of a single stretch of seabed.
