The Bog Irish Bar & Pub general manager Greg Wilson, of Dunedin, said St Patrick's Day was easily the busiest day of the year for the George St bar.
Last year, Paddy's Day was on a Tuesday and he expected there would be more revellers out tomorrow because it was a more popular day to drink.
‘‘It should be a goody.''
He expected patrons would start drinking the more than 700 litres of stout in stock when the doors opened at 8am tomorrow.
‘‘We get a lot in for a champagne and Guinness-type breakfast and they trickle in throughout the day. At night-time you get more people and it gets a bit messier.''
The Craic Irish Tavern general manager Bruce Hoffman, of Dunedin, said the Octagon bar was stocked with 650 litres of stout and 200 litres of Irish cider.
Traditional Irish fare would be on offer, he said.
‘‘Fingers crossed, we can get hold of some oysters,'' Mr Hoffman said.
The number of revellers joining the celebration would depend on the weather.
A fine day attracted a ‘‘huge'' crowd and the tavern easily reached its capacity.
MetService meteorologist Arno Dyason said the weather would be fine across Otago tomorrow.
In Queenstown, Pog Mahone's Irish Pub general manager Tom Cairns, said the bar had 2000 litres of stout in stock for Paddy's Day and the long weekend.
Revellers travelled from as far as Rakaia and Invercargill to celebrate Paddy's Day in Queenstown.
For the celebration, the bar was holding a game of Gaelic football.
‘‘It's not all about the drink,'' Mr Cairns said.
The manager of another Queenstown pub, Morrison's Irish Pub, Sean McSparron, of Queenstown, said he doubted the centenary of the Easter Rising - an armed insurrection in Ireland during Easter Week in 1916 - would see an increase in patronage in the Queenstown bar on St Patrick's Day.
The Irish ex-pat from Killarney, in southwest Ireland's County Kerry, said the centenary would mean a bigger Paddy's Day celebrations in Ireland but it would not increase the revelry in Otago.
‘‘Not this far away, I doubt it.''
