But while the ceremony was grandiose, in language at least, the day-to-day duties of JPs are humble and behind the scenes. The role mainly includes witnessing signatures, documents and affidavits.
Ms Paki said she wanted to serve the community.
"I guess everyone says that ... But I want to alleviate stress for the communities that might have to travel. Bearing in mind I live in the Bream Bay area and there's no public transport."
The job of a JP was not always so gentle. Keepers of the peace have existed in England since ancient times but a law change under Edward III in 1361 gave them power to try felons and take the title "Justices".
King Edward's law stated that the justices "shall have the power to restrain the offenders, rioters, and all other barators [brawlers], and to pursue, arrest, take and chastise them according to their trespass or offence".
The idea was that each community needed someone who was learned in the law. To this day in New Zealand justices are often assisted by court officials and some have the power to preside over minor court matters, such as traffic infringements.
Thomas Kendall was appointed as New Zealand's first JP, based in the Bay of Islands, in 1814.
The first female JP in the British Empire was New Zealander Elizabeth Yates, also the first female mayor in the empire and elected by the Onehunga Borough electorate in 1893. She took up the JP role in 1894 ex-officio, like Mayor Mai.
After this Mrs Yates occasionally presided over cases, but only those involving women.
There was resistance to her taking both the role of JP and mayor. The town clerk and four of her councillors resigned immediately, and three other councillors set out to sabotage her policies.
