"An initial search of the creek has already been undertaken," Detective Sergeant Richard Quested said.
"But to complete a safe and thorough search of the pond, which is several feet deep, it is appropriate to use the dive squad."
Mr Quested said police remain confident there was no indication of foul play in Mr Mackle's disappearance.
"We are continuing to call for any information from the public that may assist in locating Mr Mackle, including any sightings of his taxi on Wednesday night, December 11 or the early hours of Thursday, December 12."
Anyone with information is asked to contact Christchurch Police on 03 363 7400.
