A police spokesman said the investigation was progressing, however there were no updates over the weekend.
Mr Singh's father had arrived in New Zealand and was in Christchurch yesterday.
Mr Singh was found lying amid shards of glass outside his Hillary St home last Monday morning.
Detective Senior Sergeant Kallum Croudis said evidence had suggested a sharp weapon as opposed to a shard of glass had been used. He said it was "highly probable" there was a fight of some kind at the address, but police were keeping an open mind with regards to a motive.
The broken glass at the property was "deformed" and this evidence was being used to help police determine the time of death.
