Calls for a 24-hour police presence in Auckland's Karangahape precinct before the City Rail Link opens.

Two men are due in court today - after one person was seriously injured on Mercury Lane last night.

Several people were arrested in the weekend after a bar fight nearby.

Karangahape Precinct Collective chair William Keung says there's been a persistent series of anti-social incidents in the area - and concerns have been raised.

"It seems to draw in that crowd that's actually causing the issues and challenges that we've got in play...there's been numerous callouts."
