Mitchell Moss, 22, is charged with supplying and possessing psychoactive drugs.
A 30-year-old man, who was granted interim name suppression, is charged with supplying and possessing psychoactives and possession of a pipe for consuming methamphetamine.
Both men were remanded on bail until October 11.
Conditions of their bail include not associating with each other or using drugs including synthetics.
Makikiriti and Taneao's funerals were held this week.
The 58-year-old appeared in the North Shore District Court yesterday on a raft of charges relating to the seizure of synthetic drugs police say would have had a street value of $1.5 million.
Thompson, who voluntarily returned from Australia last week just before his arrest, is facing four counts of importing a psychoactive substance as well as charges of manufacturing and possession with intent to sell.
Last week Detective Inspector John Sutton said Thompson's arrest, part of ongoing Operation Tiger targeting the importation of synthetics, was "significant".
Thompson was remanded on bail until his next appearance on conditions including not accessing the internet.
Police are calling on anyone with information about people making or selling synthetic drugs to contact them immediately.
"We need to do more, we need your help," said Waitakere Detective Sergeant Kelly Farrant.
"We need you to tell us who is supplying the drugs that are seriously harming our whanau.
"We can't do this alone.
Farrant said anyone who had information about those making or distributing the drug should call their local police immediately.
"If you wish to remain anonymous, call Crimestoppers on 0800 555 111," she said.
