A coroner has recommended police officers be required to carry Tasers following an inquest into the shooting death of an armed man during peak hour at Sydney's busiest train station.

Danukul 'Dan' Mokmool, 30, was shot in the head and died after he held up a florist with a broken bottle and then ran at police on the Eddy Ave concourse at Central station on July 26, 2017.

None of the four police officers involved in his death had a Taser at the time, an inquest into the incident was told.

Deputy state coroner Elaine Truscott on Monday found Mr Mokmool was shot by police while 'experiencing a psychotic episode'.

She recommended that consideration be given to amending procedures for Tasers 'so that officers are required to carry a Taser absent good reason not to'.

Mr Mokmool entered the Eddy Avenue Florist at Central Station and held up a 73-year-old man inside with a piece of broken glass.

When police officers arrived on the scene, the elderly florist had escaped Mr Mokmool, who remained inside and was self-harming.

An attempt by one officer to use pepper spray on Mr Mokmool failed and he was fatally shot as he ran at a plainclothes police officer.

He was holding scissors and had screamed out for them to shoot him.

None of the four police officers on the scene was carrying a Taser.

Deputy state coroner Elaine Truscott on Monday recommended that consideration be given to amending police standard operating procedures so that 'uniformed officers performing frontline duties are required to carry a Taser absent good reason not to'.

The coroner found that police policy was to issue Tasers to uniformed officers undertaking response policing and plainclothes officers weren't authorised to carry them.

However, one of the two uniformed officers present on the night Mr Mokmool was killed told the inquest he considered it to be a 'personal choice' whether or not to carry a Taser.

He didn't believe he was required to carry one.

The coroner found that even if a Taser had been available to police the end result may well have been the same.

'However, the fact remains, a Taser was not an available tactical option when it could or should have been,' she said.

Ms Truscott found Mr Mokmool was usually a 'gentle and kind' person.

She hoped his family could put the inquest behind them and hold onto their 'memories of (him) as the son and brother they knew'.

In May the court heard from the officer who shot Mokmool, saying he had no choice.

'I didn't want to (shoot him) but he really gave me no choice,' Senior Constable Frederick Tse told the NSW Coroners Court.

Snr Const Tse told the inquest into Mokmool's death he and three other officers had arrived 20 seconds earlier on the concourse to see an armed man pacing in a small florist shop and a big crowd of commuters watching on.

'He obviously realised we were police and said to me 'I'm not giving up',' Snr Const Tse said.

Snr Const Tse said Mokmool had 'basically pushed all other options out'

'The way he said it wasn't a plea or an aggression. It was like he was stating a fact, 'this is how it is'.'

After police drew their guns and demanded Mokmool drop his weapons, Snr Const Tse said he saw one officer fire a jet of capsicum spray towards Mr Mokmool but it had no apparent effect.

'A second or so later, he looked at me and yelled 'I'm going to kill you',' Snr Const Tse said.

'His demeanour changed and he just charged... in the running posture but running with his blades.'

Snr Const Tse said he moved about three paces back but realised the 30-year-old was quickly closing the seven-metre gap between them.

'He got within three metres, I let off three rounds. He fell to the ground,' he said.

Snr Const Tse said Mokmool had 'basically pushed all other options out'.

'If I had more time, I could have tried a different tactic but there was really nothing else I could have done.'
