Ms Blair opens her kit full of brushes, powders and gadgets used for finding, taking and lifting evidence. She scours the bathroom for clues, leaning precariously out the window to reach every possible surface. And then, jackpot! - a partial but detailed fingerprint in a place where it should not be.
From a dusting of magnetic black fingerprinting powder the evidence emerges, and is lifted, sealed and labelled for processing.
"Sometimes you think there's not enough in the print, but there is and you get a hit. Sometimes you get really nice fingerprints," Ms Blair says.
While she examines, her partner Brett Charles speaks to the victim and her partner. He explains that a fingerprint has been found and that it may lead police to the person responsible for the burglary.
"It's not a CSI moment though. Don't expect me to ring you today," he tells them.
"The quickest fingerprint match was 15 seconds - the longest 12 years."
The Herald joined the pair on a normal Saturday shift. Their job is to visit people who have been burgled, collect evidence and give safety information to the victim.
The day starts with Ms Blair selecting which jobs can be attended and notifying the victims.
They start with five houses but will do more if they have time.
"We run through with them what our role is going to be. That depends on what evidence we find, what evidence is available as to whether we take it further," Mr Charles says.
"We try to attend the burglary as quickly as we can. But, we are dependent on the victim. Obviously at the end of the day we don't want to cause them any more stress than they've already had. We want to be as less intrusive as possible."
While they aim to get to every burglary, there are some they do not attend because there is not enough for them to do.
"But, we do talk to them over the phone and if they want us to attend, we will certainly go and speak to them. For some people it's a reassurance thing, they just want to actually see someone."
Neither are sworn police officers - but both are highly trained. Ms Blair worked in a microbiology lab for 11 years, and Mr Charles was a police officer in the UK.
Their first job for the day is with a young New Windsor couple who came home to find their bedroom window prised open and their belongings ransacked. The thief took laptops and a camera and as Mr Charles photographs the scene, Ms Blair talks to the couple about what is missing and what they can do to secure their home.
Condensation on the aluminium windowframes has made fingerprinting nearly impossible. But Mr Charles opens his hefty black tool box and starts brushing powder over the disturbed surfaces.
The team does not get any prints at this house. But their presence assures the couple the police are doing their bit to find the intruder.
Less than an hour later, they are at a much messier burglary in Mt Roskill. Burglars have smashed through the front door, rammed a smoke alarm up into the ceiling after mistaking it for an alarm, and stolen a rare ornament and a flat screen TV.
Ms Blair uses black powder to dust white surfaces and vice versa.
"There are different powders for different surfaces. There's a partial print here on the door handle, but it's not very good," she says.
She also has a range of brushes - feather, fibreglass and magnetic - and uses an oblique light to get an even clearer view of the surfaces she's examining. Again, there are no prints. But the homeowners say they feel much more relaxed and secure just by having some police interaction.
Next up, a block of flats in Mt Roskill that the pair have visited twice before. This time, a door has been forced open and thousands of dollars of gold jewellery, hidden around the house, stolen.
The unlucky streak continues - there are no fingerprints or evidence to be found. But the mere presence of "police" has reduced the victim's fear and distress.
After attending the last scene, it's back to the office to file evidence and finish paper work. There's not been a great haul of prints today, but that's the way it goes some shifts.
As Ms Blair says - you just never know what you're going to get.
