Moratorium to Save the Aramoana/Spit and Murderers Surfbreaks.

This is a Petition on a new Coastal Permit Application
RNl1.153.01 by Port Otago Ltd lodged on the 19th of August 2011 to dispose of dredge material at Aramoana Beach, The Spit and Hayward Point.  We, the undersigned request:

That there should be no offshore dumping at the Spit/Aramoana and Heyward Point sites until a basline survey is complete and;

2. That wave modelling is carried out by appropriate scientists in this field based on the survey results, to ascertain any possible adverse effects from dredge deposits on the surfbreaks at Aramoana and Murdering Bay, which are protected surf breaks under NZCPS 2010"

With consideration of Coastal Permit Application RNl1.153.01 by Port Otago Ltd



We the undersigned,

Request that Otago Regional Council consider the impacts of adding to the spoil mounds at Aramoana/Spit and Heywards Point offshore dump sites on the Nationally protected surf breaks at Aramoana and Murdering Bay.


When swells travel toward a beach, a great deal of the energy lies under the surface, much like the profile of an iceberg.

When a swell encounters a rise in the seafloor it slows, and rises. The friction creates drag, dissipating the swells energy, as the swell encounters the shore, it again rises and 'shoals' then finally breaks as a wave, thus dissipating all its energy. Once the spoil grounds reach a level where the waves break continuously over the spoil mound, only degenerative effects will be observed in the inshore surf conditions.

Martin Single stated in 2003 that the spoil mound at Aramoana/Spit was already full,  with 60% retention of spoil.  Now in a bigger swell, waves begin to shoal over the Aramoana Spoil mound.( see video evidence above).

The Aramoana spoil mound is currently at a depth of 5-7 metres from the surface. Continued dumping of 600,000 cubic metres  of dredged spoil over the next 3 years will raise the mound by up to 2 metres.


These surfbreaks are recognised for their quality in the New Zealand Coastal Policy Statement 2010, policy 16,  and cannot be mitigated for, they must be protected.  


We believe that Dunedin is in danger of losing a unique amenity to the surfing community nationally and internationally.  These surf breaks are major draw cards for attracting students to study in our city. 

Please study the effects on Wave Quality with appropriate scientists that specialise in this field before deciding on further depositing of spoil at these sites. 




Thank you
