Four Maori sovereignty advocates in Whangarei have been jailed despite also being punished by their hapu.
The group, including National MP Tau Henare's nephew, had sought leniency after being "sentenced" to two years of "hapu service".
Three of the four were caught with cannabis worth up to $52,000 after police drove past a Tikipunga house and smelt the cannabis from the road, despite their patrol vehicle's windows being up.
Mr Henare had written a letter of support for Maihi Paraone, 27, who, together with his father Mitai Brown, 52, and uncle Stephen Brown, 43, had been found guilty by a jury of possession of cannabis plant for supply.
Another relative, Jason Tua, 44, was found guilty of possession of cannabis oil for supply.
