Meghan has shown her penchant for blue during the tour.
She stepped out in a navy dress earlier in the day while attending a powhiri and luncheon in Their Highnesses' honour at Te Papaiouru Marae, where the royal couple were adorned with traditional garbs.
The duchess wore a specially woven korowai representing her mana and position as a powerful woman.
At the marae, Prince Harry began his speech in te reo, and every line was greeted with applause, as school kids in yellow polos, warriors with taiaha and korowai-clad kuia looked on.
"Thank you so much for the beautiful cloak you have gifted myself and the duchess," said Harry, adding it would be treasured in the family.
He then led the waiata himself, singing all of the words to Te Aroha in te reo.
The Duke of Sussex was handed a carved weapon during a visit to Rotorua – and warned he should not take it to Twickenham when England play New Zealand.
Harry and Meghan entered into the Tamatekapua Meeting House both wearing a Maori cloak – called Korowai – which is intended to be a protector.
He was given a tewhatewha, a Maori weapon with a point at one end and an axe at the other.
Trevor Maxwell, on the local district council, said: “I am sure you are going to Twickenham when the All Blacks play England on November 11 – make sure you don’t take that.”
