A 28-year-old man had been shot three times in the stomach.
He was taken to hospital in a serious condition and has since had surgery. He is due to be released later today.
Police were also looking for Levin man Wheturangi Tauhore. Detective Sergeant Grayson Joines said police believed the 25-year-old could assist with their enquiries.
"Police have had an excellent response from the public so far and would like to thank them for their assistance during this ongoing investigation.
"Police are still seeking a second person in relation to the incident and ask that anyone with information comes forward."
He urged Tauhore to make himself known to police and asked anyone with information on his whereabouts to contact Palmerston North CIB on 06 351 3896.
