The West Auckland supermarket at the centre of a horrific terror attack that ended in police shooting a man dead is set to open its doors tomorrow - a week after it happened. 

Countdown LynnMall, inside the LynnMall shopping centre in the suburb of New Lynn, is due to reopen after shoppers ran for their lives when a knife-wielding man attacked members of the public last Friday afternoon. 

It is understood the supermarket will open again tomorrow after a blessing ceremony today. 

A spokeswoman for the company is set to give more details about the reopening of the supermarket and how staff have been coping. 

Emergency services rushed to the mall just after 2pm Friday after reports several shoppers had been injured in an attack.

Police later named the offender as Ahamed Aathil Mohamed Samsudeen, 32, who had been under 24-hour surveillance and was on a terror watchlist. 

Seven members of the public suffered serious injuries in the attack that left some fighting for their lives. Samsudeen was shot dead by police at the scene. 

'We're still coming to terms with Friday's events'

The LynnMall Shopping Centre reopened on Tuesday and a message from management on its website acknowledged the shock many staff members were still feeling. 

"Thanks for your messages of support over the past few days. We're still coming to terms with Friday's events, but the positive messages from our extended LynnMall whānau have been greatly appreciated. 

"We feel lucky to be part of such a tight-knit community and the appalling actions of one person won't detract from that." 

The mall has a number of essential services and businesses on site, including a vaccination clinic, pharmacies, a medical centre and several bank ATMs.
