In a 50-second video shared on Facebook, the suspect can be seen pointing a metal bar at officers before moving towards a short flight of stairs.
As the man continues to advance towards the officers, the police can be heard warning him to stop before finally discharging a Taser when the man fails to comply.
The suspect falls backwards and officers are seen running towards him.
The police said the man and the auxiliary officer were both conscious when taken to hospital, with the auxiliary officer sustaining minor injuries.
The metal bar was seized and the 31-year-old was subsequently arrested for voluntarily causing hurt by dangerous weapon, criminal force to deter a public servant from discharge of his duty and suspected drug-related offences.
Police investigations are ongoing.
