His son and daughter told him not to go and that they would instead pick it up.
But Gurmej loved walking. The former farmer had built a lifelong health regimen based on going for a daily walk and eating a banana and mango each day.
Setting off from his daughter's Papatoetoe home, he was crossing Great South Rd, near Hunters Corner Plaza, at 3.40pm when he was struck by a silver Honda Insight.
The impact threw him several feet onto the footpath where he landed on his head and shoulder, son Bachan Singh Lally said.
When Bachan arrived at Middlemore Hospital, his dad was alive but on a ventilator.
"The doctors tried to stop his bleeding but there was too much damage to his head," Bachan said.
By 7.30pm Gurmej passed away without regaining consciousness. His family never got to say goodbye.
"I am alone now," Bachan's mother told her son in her grief.
Counties Manukau Police Inspector Kay Lane has appealed for crash witnesses to come forward.
The car's driver allegedly failed to stop and check on Gurmej after hitting him. However, police said they later located the driver, who was now assisting officers with inquiries.
No charges had been laid and the investigation was ongoing, police said.
Ten years earlier, Gurmej's extended family had also been thrown into grief by the tragic death of Lovedeep Singh.
The energetic Papatoetoe 6-year-old had been on his way to watch a traditional Punjabi kabadi (wrestling) tournament in March 2010 when the van he was in lost control on the Southern Motorway.
Lovedeep had been a much-loved relative, who often visited Bachan's Wishing Well of India restaurant in Orewa, but barely touched his meal "because he would talk too much with his mum".
Similarly, 87-year-old Gurmej had been a popular figure in South Auckland, where he would head to the markets to chat and buy his bananas and mangoes.
He migrated to New Zealand with his wife in 1993, just a few years after son Bachan came here to study.
Gurmej earlier worked hard on the family farm in India's Punjab region, growing sugarcane, rice and vegetables.
It was his idea Bachan should go abroad and study.
