"I was probably in international waters. I was probably in Australian territory to tell you the truth, I was that far out. I had wetsuit trousers on... I pulled them down and I balanced on the edge of the jet ski, holding onto the steering handle and managed to do my business."
Gillies leaned back in her chair at Richardson's story before telling him it was "revolting".
Garner said it was "probably illegal" - and he may be right.
The Auckland Council told the Herald that under Auckland Unitary Plan guidelines, disposal of untreated sewage from a vessel into the ocean in all bays and inlets is banned.
That rule covers all areas within 500 metres from shore and in water less than five metres deep.
The AM show with Mark Richardson, Amanda Gillies and Duncan Garner.
The act is also not permitted within 500 metres of an "aquaculture activity and Mātaitai Reserve," 500 metres from high water springs and 200 metres from a marine reserve.
Discharged untreated waste that does not meet these requirements is a prohibited act under the Resource Management Act 1991.
If Richardson were to be found breaking these rules, he could be liable for a fine of up to $2000.
