A Te Puna man brutally beaten at his home in 2012 has given evidence in Tauranga District Court today about the attack which left him with facial injuries and a concussion.

Andrew Duncan and his son Gary described the night a group of people came to the family's Te Puna Station Road home armed with numerous weapons.

Police at the Te Puna home in 2012 where a man was allegedly beaten in a attack.

Chaos was the word bandied about in court today as the trial for Jack Simon Ake, 52, Rihari Jarrod Borell, 28, Jasmine Hira Borrell, 25, and Derek Michael Drewery, 27, entered its second day.

Ake is charged with injuring with intent to cause grievous bodily harm and wounding with intent to cause grievous bodily harm.

Jasmine Borrell is charged with wounding with intent to cause grievous bodily harm, injuring with intent to cause grievous bodily harm, assault with intent to injure, assault with a weapon, common assault and possession of an offensive weapon.

Rihari Borrell is facing two counts of injuring with intent to cause grievous bodily harm and two counts of possession of an offensive weapon.

All three are denying the charges at a jury trial in Tauranga District Court this week.

In court this afternoon, Andrew Duncan recalled being woken by a loud noise outside his property just after 11pm on the night of November 23, 2012.

This noise was followed by one his son's yelling 'Dad, they're attacking us”.

The call for help made Andrew jump out of bed, throw on a pair of shorts, and grab a piece of wood and his dog as he exited his home through his garage.

The group of people left in a vehicle and Andrew went back inside with his family and waited for police in the lounge.

'As we were in the lounge, we saw some lights come into the driveway, so I made my way outside as I thought it was the police.

'I saw more car lights, which was immediately followed by the sound of breaking glass. A mass of people came round from behind the cars and started moving towards the house.

'I told them they had to leave several times but more people kept coming forward. Then the fighting erupted.”

Andrew told the court he remembers an altercation with someone holding a bat, and the next thing he had been knocked unconscious.

'The next thing I remember is waking up and standing next to my son who had my shotgun. Once he knew I had my faculties, he (Kevin) handed me the gun and went back inside to get more ammunition.”

When Kevin returned, he reloaded the shotgun and fired more warning shots overhead of the crowd which then began to retreat.

Andrew said Kevin followed the group down the driveway to make sure they had left the property.

The family then retreated back into their home and waited for police to arrive.

Once police cleared the scene, St John Paramedics were let into the property to treat Andrew, and one of his son's friends injured in the fight.

Earlier this morning, the court heard from Andrew's son Gary, who described hearing breaking glass and a deafening sound of violence when a 'mob of people” arrived at their property and made their way up the driveway.

'Everyone I saw was either armed with a pipe, spade or some sort of other weapon.

'I lost sight of Dad (Andrew Duncan) who disappeared in the group.”

Gary went on to describe his actions on the night and how he tried to help defend his family.

'I remember feeling helpless. I ran inside to the kitchen and grabbed a couple of kitchen knives.” It was at this time Gary remembers his brother Kevin running back inside to get more ammunition after firing a first set of warning shots at the crowd with his father's 12 gauge shotgun.

The trial is expected to run through until Thursday.
