Ardern said her parents had spent their honeymoon tripping around Northland, including a visit to Waitangi Treaty Grounds.
The Prime Minister also came in for some teasing over her wedding arrangements while she was being welcomed to Kawakawa by Ngāti Hine kaumātua Waihoroi Shortland.
Referring to reports of a menu dispute with a wedding venue in Gisborne, Shortland joked Ngāti Hine would cover the costs of her upcoming nuptials in Northland.
"We'll even allow any chef of your choice to supervise the hāngī," he said.
Shortland — who has once before welcomed Ardern at the same spot in Kawakawa — said in future she would not be welcomed as a guest but would instead sit with the hau kainga (home people).
''Ko tangata whenua koe,'' he said, meaning, "you are one of us".
Ardern and Gayford originally booked the Bushmere Arms outside Gisborne for their big day but the deal broke down amid disagreements over catering.
They are believed to be still aiming for a Gisborne wedding this summer.
Since being first elected as PM in 2017, Ardern has spent five days at Waitangi every February. Previous prime ministers have stayed for a day or two to mark the anniversary of the signing of the Treaty of Waitangi or in some cases have skipped the commemorations altogether.
