Last Friday, both saw a large brown trout, and Miss Coulter-Jeffrey, a supervisor at the Te Matiti Cafe in the Business School, vowed to come back that afternoon to catch it.
''It was there at the end of the day so we walked to my car, grabbed two rods, but no net and no tackle box, as I honestly thought we would spook it, but I thought it would be worth a shot.''
As it turned out, it only took five minutes to hook the fish and another five minutes to land it.
It weighed 3.6kg (8lb).
''It's a very good-sized fish, especially for the shallow depths the Leith is running at at the moment,'' she said.
Although it meanders through urban Dunedin, the Leith is home to some sizeable fish, Miss Coulter-Jeffrey said.
''I know the pools where they sit.
''They get up so far, then they have to wait for rain to fall to goup any further.
''They literally become sitting ducks when they're waiting for rain.''
Miss Coulter-Jeffrey is a dedicated angler.
After catching her trout, she landed three more sizeable fish on the Taieri.
''I caught a 9-1/2 pounder (4.3kg) up at Hindon three years back and I have caught bigger salmon ... but it's my second-biggest river fish.''
Her trout became a treat for a child-care worker at Te Pa - a Christmas present for looking after Miss Coulter-Jeffrey's daughter.
