Bottom line: This ionisation smoke alarm is very good at detecting fast (flaming) fires. But it’s extremely poor at detecting slow (smouldering) fires – and it doesn't come with a long-life battery. There are more effective smoke alarms than this.

About our test
Our test was conducted in the fire laboratory of the Building Research Association (BRANZ). We purchased 3 examples of each model. Our results are the average of the performances of the 3 examples.
The alarms were fixed to a ceiling panel in a mocked-up hallway adjacent to the door opening of a fireproof room (which was about the size of a single-car garage).
In both tests, the smoke density was measured at the location of the alarms using a laser light-source and detector.

Nothing - BRANZ testing shows this alarm is "EXTREMELY POOR" at detecting the early smouldering stage of a fire! However, if the alarm has not been disconnected due to incessant false alarms, it will eventually sound - but by then it may be too late for occupants to escape (see Fire Brigades position below)
W A R N I N G!
Ionisation smoke alarms have been proven by Australian Government (CSIRO) testing to have life-threatening defects.
Take the NZFS's advice - ONLY install photoelectric alarms.
The Australasian Fire & Emergency Service Authorities Council (AFAC) is the peak representative body of all New Zealand and Australian fire brigades.
AFAC's position of 01 June, 2006 states:
"That all residential accommodation be fitted with photoelectric smoke alarms . . . Ionisation smoke alarms may not operate in time to alert occupants early enough to escape from smouldering fires."
No, this product has too many drawbacks.
