The Duke and Duchess of Sussex braved the rain to visit Courtenay Creative in Wellington - which bills itself as "a place to Connect, Collaborate and Cultivate".
The event they were attending was aimed at celebrating the city's thriving creative arts scene.
While Prince Harry shunned a tie, opting instead for an open-necked shirt and jacket, Meghan wore a white tuxedo dress with pockets by Maggie Marilyn.
The "Leap of Faith" blazer dress retails for $1020 and is ethically made in New Zealand.
Maggie Marilyn is a New Zealand based fashion brand that launched in September 2016.
According to the brand's website, the Maggie Marilyn collections "are delivered with a sense of confidence and modern luxury, taking into consideration the ethical and environmental impact of contemporary fashion".
On arrival at Courtenay Creative, the Duke and Duchess happily posed for a photo alongside an array of ghosts and ghouls for the Halloween-themed event.
Courtenay Creative's most recent exhibition - called Things That Go Bump In The Night - is billed as an exhibition of "haunting artworks" from world-renowned artists.
"‘Things That Go Bump In The Night’ brings together some of the worlds most celebrated fantasy horror artists," the site's Facebook page reads.
Earlier in the day, the Duchess of Sussex said young people and their sense of self-worth can become “really skewed” by social media.
Meghan was speaking to youngsters about how unrealistic images on sites such as Instagram can have an impact on mental health.
The duke and the duchess attended a beachside cafe in Wellington, New Zealand, and were praised for their efforts in highlighting mental health issues.
Meghan - who was dressed casually for the occasion in her favoured black Outlander jeans and a Jac & Jack top and a Club Monaco coat - spoke to staff and volunteers from Live for Tomorrow, an online youth programme focused on reaching millennials with messages of positive change, and said: “Young people find it so difficult.
“You see photos on social media and you don’t know whether she’s born with it or maybe it’s a filter.
“Your judgment of your sense of self-worth becomes really skewed when it’s all based on likes.”
The couple spent 45 minutes discussing mental wellbeing and learnt about initiatives and programmes supporting mental health in New Zealand, with a focus on youth.
The Sussexes were at the Maranui cafe in New Zealand’s capital, the latest stop on their 16-day tour which has also seen them travel to Australia, Fiji and Tonga.
Harry spoke about his own struggles with mental health during the conversations, admitting that it took him years to confront his own inner turmoil.
He said: “It took me about three or four years to start the journey and then after that you still have to find the right people to speak to.”
