Justice Lang calls an end to the fourth week of the trial, until 10am Monday, when Reeves will continue to give evidence about what he found on Hanna's phone.

"We're getting towards the tail end of the Crown witness list," the judge tells the jury.

He says the Crown case should finish early next week. 

The trial is set for six weeks and next week will be fifth.

"As far as I can tell I think we are still on target," but we'll know more next week, he says.

Justice Lang directs the jury to keep an open mind.

"There's a long way to go," he says.

"Don't come to any conclusions at this stage, it's far too early for that, and again just remember we're getting to the sharp end of the trial, so it's just absolutely essentially you don't discuss this case with anyone over the weekend."

The last interaction was on April 4 at 10.47pm, when it was plugged into a charger.

Reeves says the final entry was a calendar appointment Hanna had created for "dinner with PJP", saved for April 5, at 7pm.

The police digital forensic unit also extracted data from Hanna's Iphone 8.

At 6.06pm, April 4, she sent a message to Rose Hanna.

About 7pm and 8pm she sent messages to colleague Sharon Alabastro, whom the trial heard from earlier.

The drive included more deleted naked images of Ashton.
Six images and three videos were found on another drive - most were of Ashton.

Another drive held 51 videos, 43 were pornographic - 12 of Ashton - and 380 photos, 174 of which were pornographic, many of Ashton.

There were also 35 photos of Pauline Hanna, fully clothed.

There were also numerous naked selfies of various other women sent to Polkinghorne, Reeves said.

The drive also held screenshotted and saved Whatsapp conversations with Madison Ashton, covering arrangements to meet for sex.

The police also found an invoice from the Jake Ryan Group for four hours for $2000 on November 10, 2017.

There was also a text worker to sex worker companion Lee, who has already been mentioned at the trial, "in regards to meeting her and having sex with other males".

More drives held more porn videos and more images of Ashton and Lee.

"There was also multiple saved images of knot-tying techniques," says Reeves.

Yet another drive had about 4000 images of Ashton, under her alias Christine McQueen.

Another photo showed a meth pipe next to a glass pipe with "Sweet Puff" written on the side.

"I've seized many meth pipes," says Reeves. New ones are clear and used ones are frosted.

Polkinghorne can be seen in a reflection.

"He's naked while taking a photo."

Earlier evidence showed the meth pipe found at Auckland Eye had Sweet Puff written on the side.

An investigation conducted by the firm's lawyers could not identify who left the pipe in a laser room in October 2020.

Reeves tells the court six USB drives had images or data of note. One had 113 images, 20 were pornographic, 13 of Ashton.

There were 31 deleted videos, most pornographic.

Another had a loan agreement document that had Polkinghorne as the lender and Madison Ashton as the borrower, to the amount of about $90,000.

Videos on the drive were taken inside Ashton's apartment and Polkinghorne appeared to be filming as his reflection was in the mirrors.

Further images showed Ashton in a bedroom with her Chihuahuas.

The images were taken in June 2019.

7.03am to 8.05am: the phone was locked into a landscape orientation, Reeves says. 

8.06am: flight mode was switched off and Whatsapp used, but the messages were deleted, Reeves says. 

8.10am: the mobile phone app makes an outgoing call, later confirmed to be to Ruth Hughes, Polkinghorne's sister.

Reeves moves to the many hard drives and USB sticks police seized during their investigation.

He reviewed 18 USB drives in total, he says, and six of the drives contained data of interest.

A photo taken on June 22, 2019 was recovered from the first drive.
The investigation team later added rectangles to areas of interest to the photo, which shows a woman on a bed. Her face is not visible. But two Chihuahuas on the bed led police to believe the woman was Madison Ashton.

1.17am: the note application was used.

1.19am to 1.20am: the photos and videos app was used.
1.45am to 1.49am: the photos and videos app was used again.

2.04am to 2.05am: the photos and videos apps was used again.

2.16am: an email was received from Norton Lifelock.com and the photos and videos app was again used.

2.44am: the phone's display was switched off.

6.46am to 7.03am: the phone was unlocked and the display was on.

The photos and videos app was used until 8.05am - the orientation changed on the phone around the same time.

8.05am: the mobile phone app was used, but because flight mode was still on, there was no connection.

Also at 11.16pm, the phone was locked and the display turned off.

At 1.10am the phone was unlocked and Whatsapp was accessed until 1.17am.

Reeves does not know what Whatsapp was used for that night. The trial has heard messages before April 5 are missing, despite screenshots showing earlier messages.

The phone was then put in flight mode.

He returns to Polkinghorne's iPhone.

Reeves said the data he extracted showed all sorts of events in the "acute period" - the days before Hanna's death - including when a phone was used, locked, when its settings were changed and other changes.

From that, he produced a timeline of the phone's activities.

Starting April 4, on 6.17pm, the day before Hanna is reported dead, Polkinghorne received a message from Hanna stating she was on her way back, referring to a visit to the tip.  

Two hours later, at 8.17pm, Polkinghorne gets a message from Hanna stating "more than that I think P".

At 10.01pm a Safari web search on Polkinghorne's phone looked for a documentary on Three Now called The Price of Fish, Reeves sys. 

At 11.16pm, the Whatsapp application on the phone was accessed.

After a short recess, Prosecutor Brian Dickey continues to lead Detective Andrew Reeves through his evidence.

Reeves now refers to messages taken from an iPhone belonging to Madison Ashton. The trial heard earlier her phones were seized by police when they arrived at a Mt Cook Lodge where she was staying with Polkinghorne 25 days after Hanna's death.

The messages show screenshots of videos from Polkinghorne's police interview. Another video shows a photo of the wound on his head.
