Featured Collection
Matariki 2026–2027
Three colourways — ivory, midnight, and neon. Same data, completely different mood.
For the person who has a beach they keep going back to.
THE METHOD
Mapping the Tides.
The source
We take raw tide data from LINZ and turn it into something worth hanging. No decoration, no embellishment — just the ocean's rhythm, made visible.
The form
Harmonic data reduced to its essentials. Each matrix is built from the same numbers that ships and surfers rely on — reduced to what actually matters.
The file
Rendered as vector geometry, not pixels. Print it at A4 for your desk or A0 for a wall — every line holds.
Locally printed

Frequently Asked Questions
Why does the poster show 2026-2027?
The collection follows the Māori New Year. Matariki rises in June/July 2026, and the poster covers the full year until it rises again — July 2026 through June 2027.
Does the poster show the whole year?
Yes. Twelve months, laid out in a 12×31 matrix. Every day of the tidal year, in sequence.
Is the data accurate?
The data comes directly from LINZ — the same source used for official New Zealand tide tables. Every curve is calculated, not estimated.
What do I get when I purchase?
A physical print — framed or unframed, shipped anywhere in New Zealand — or a high-resolution PDF you can take to any print shop. The digital file scales to A0 without any loss. Prints start from $39 NZD.
