The Otago Regional Council yesterday confirmed it had started investigating, but further details were scarce.
Hector’s dolphin advocate Genevieve Robinson, of Christchurch, contacted the Otago Daily Times yesterday afternoon to provide pictures and a video of the work, piles being driven at the pontoon below the jetty, as it was under way at the Dunedin City Council-owned jetty yesterday.
She said she contacted the Otago Regional Council after being supplied the video and was told by ORC staff it was a ‘‘non-permitted activity’’.
‘‘If people are doing this without a consent, we should be very worried,’’ Ms Robinson said.
‘‘I can’t stand this stuff, when they think they can get away with it because they’re a council — it really irritates me.’’
An ORC spokesman said the council was checking with the DCC what the work involved and whether it was consented.
‘‘Once initial investigations are completed, we will be in a position to comment further,’’ the spokesman said.
The DCC did not respond to ODT questions yesterday.
DCC documents show the jetty is owned by the city council and is located about 500m north of Wellers Rock.
Monarch Wildlife Cruises and Tours owner Neil Harraway, whose company uses the jetty, said the project was not a Monarch project and referred comment to Port Otago and the DCC.
Port Otago chief executive Kevin Winders referred comment to the DCC, as the jetty’s owner.
University of Otago zoology professor Liz Slooten said if there had been a public notification process she ‘‘probably’’ would have opposed the application over the percussive type of work when there were options which achieved the same result, that did not create the same disturbance to the marine environment.
‘‘The noise above water is pretty horrendous, but the noise below water is much worse, because sound travels so well in water,’’ she said.
DCC documents state that Wellers Rock, the ‘‘actual rock area’’ is a historic reserve managed by the Department of Conservation.
Doc was approached for comment late yesterday.
Last week, the ODT reported up to $10,000 being spent on a project to stop the degradation of the historic site.
The DCC, Doc and Te Runanga o Otakou were making a combined effort to protect Wellers Rock.
However, that project was focused on car parking issues at the site.
