The force that a prison guard used on a prisoner after an attack on guards was "excessive and disproportionate," the trial was heard against three officers.
The claim comes as graphic footage of the incident in Auckland Prison, played before the jury, showed the attack and the reactions of the officers, which led to a broken anemone's prisoner.
The accused are Wiremu Paikea, 34, Desmond Faafoi, 26, and Viju Devassey, 31.
Paikea is accused of causing serious bodily harm, Faafoi is accused of assault with the intention of injuring and Devassey is accused of having perverted the legal process after he purportedly removed a camera from the incident.
* Crown: guard kicked prisoner in head
All three deny the charge.
On Tuesday afternoon, Rob Hoogenraad, senior consultant for tactical operations, who worked for forty years part-time as Correction instructor in control and restraint, explained the limitations that are being taught to officers.
Hoogenraad said that Paikea had fitted a four-foot lock during the incident in May last year.
"At that time it was not necessary because the prisoner was under control, with the person at the head and the other two officers at the arms," Hoogenraad said.
"The level of violence was excessive and disproportionate."
In the images that were played before the jury, Paikea could sit on the legs of prisoner Mitai Angell for about five minutes.
"I think he dived on the top of the foot or sideways, it seemed to be a sideways movement," Hoogenraad said.
Angell got a composite fracture on his ankle and leg and the injury is visible in the video.
Hoogenraad said that all three of the accused were up to date in their training of control and restraint methods.
But Faafoi's counsel Aaron Perkins QC questioned whether the training given to officers adequately prepared them for a real incident.
"I would say that the training is not the real one, I suggest that your training is not entirely useful," Perkins said.
The force used by the people being held during training may not reflect the force used in an actual incident, he argued.
The images played in court showed the first attack on Faafoi.
The prisoner of Samuel Hutchin can be seen, he launches himself on Faafoi with a homemade shank, after which he is seen bleeding from head wounds.
Blood splattered and smeared on the walls and the floor as the Correction agents came in to help.
Voices could be heard during the camera images of the body and the sentences "Des", "enough, enough, enough, enough" and "camera, camera" could be heard from an unknown Correction officer.
In his opening speech at the High Court in Auckland on Monday, David Wiseman, Crown's representative, told the jurors that the incident began with prisoners who attacked prison guards.
Those prisoners were already bought in court and this lawsuit was about the reaction of the Corrections officers to that attack, Wiseman said.
On 20 May 2017 at approximately 2.30 pm three prisoners, Samuel Hutchins, Trent Wellington and Mitai Angell, were waiting in the recreation wing of the Bravo block to return to their cells on the top floor of the prison.
Faafoi was at the bottom of a stairwell with another officer.
When Wellington was halfway up the stairs, he came back and attacked Faafoi.
Hutchins and Angell then followed "Wellington's cue" and Hutchins hit Faafoi several times over his head with a handle.
In response, two Correction officers came to help Faafoi and after the prisoners were forced from him, he rushed in to "take down Angell," Wiseman said.
At that moment, Angell was curled up on the ground, surrounded by several Correction officers, and he was clearly restrained and under control, the court heard.
Faafoi then kicked Angell three times, while Devassey's body camera caught the kicks.
Todd Simmonds, Faafoi's counsel, said Monday that he questioned the "intent" aspect of his client.
"Maybe he got out, but did he have that specific purpose? I subject him, he did not," Simmonds said.

The third guard, Devassey, stands for the attack on attempts to pervert the legal process.
About half a minute later, Mr. Devassey goes up the stairs to the Command Room of the Bravo block and, says the Crown, is disturbed by the camera that records the incident with prisoner Angell, & # 39; Wiseman said Monday.
In the CCTV images, the camera is at a certain point in the direction of a garment on the ground and away from the prisoners.
Tuesday afternoon, Constable McIvor, who investigated the incident, read Devassey's statement from the day of the incident.
No mention was made of adjusting cameras in the control room.
Instead, he described how he removed a shaft from the scene of the incident and brought it to the upstairs middle office in Bravo block.
The test continues.
