Koromiko is a small rural settlement in Marlborough, strung along State Highway 1 in the valley between Blenheim and Picton. It sits closer to Picton than to Blenheim town, and it is not a residential suburb of either centre.
Dairy farms occupy much of the valley floor, with the hills of the Marlborough Sounds rising around them. Picton Airport is based here, and a timber Anglican church still stands beside the highway. A small council forest reserve protects a rare remnant of the lowland treeland that once covered these flats.

About Koromiko
Koromiko is a locality in the Marlborough District, the same council that administers Blenheim, but it is a separate rural settlement rather than part of the Blenheim urban area. State Highway 1 runs through the valley. Picton is the nearer town, and Sounds Air places Picton Airport about 8 kilometres south of Picton on the highway at Koromiko.
The land around the settlement is valley-floor country used for dairying. A Marlborough District Council soil study of the Koromiko area recorded dairy farms on alluvial soils, some poorly or imperfectly drained, at low elevation. The wider locality takes in farmland and hill country and sits within the larger Marlborough Sounds East statistical area.
There is no shopping strip, school or railway station in the settlement itself. Daily life points north to Picton for shops, the library and most services, or south along the highway toward Blenheim.
What Koromiko does have on its doorstep is an airport, a nineteenth-century church, and one of the better surviving pieces of valley-flat forest in this part of Marlborough.
The word koromiko is the Māori name for several native hebe shrubs. A district history of Koromiko has been published, but this guide has not confirmed a formal naming story or a single iwi affiliation for the settlement, so those details are left out.
History and Heritage
The Church of St John’s in the Wilderness is the settlement’s clearest historic landmark. Heritage New Zealand lists it as a Category 2 historic place. It stands at 858 State Highway 1, on the west side of the road just north of Station Road, and it is visible from the roadside.
The register records the site as private, with no public access noted on the listing, so treat the grounds as private unless you have confirmed you may enter.
A Marlborough libraries history, updated in 2025, says the timber church was opened by Bishop Suter on 4 April 1871. It was built of locally milled timber. An iron roof went on in 1883, and the building is described as still largely in its original form.
The same account says Sir Paul Reeves was baptised here, that wrought-iron memorial gates to Nathaniel and Hannah Bragg were erected in 1927, and that services have continued, weekly for much of the year and fortnightly in winter. That is a community history rather than the heritage register, so check locally if you are hoping to go inside or attend a service.
Koromiko School was a coeducational full primary for years 1 to 8. It was founded in 1873 and closed at the beginning of 2013 after the roll fell. Pupils transferred to schools in Picton or Tuamarina. The school building is no longer a local primary.
Getting Outdoors
Koromiko Forest Reserve, also known as the Collins Memorial, is a roughly four-hectare patch of remnant forest on State Highway 1.
For about 30 years before 2002, the Marlborough branch of the New Zealand Deerstalkers’ Association ran it as a deer park, with red and fallow deer, a thar, wallabies and goats, while sheep and cattle also grazed the pasture under the trees. Marlborough District Council took over management in March 2002.
An ecological survey in 2002 and 2003 found the site significant: a rare surviving piece of the alluvial-flat forests that once filled the valleys north of the Wairau, and the best example of valley-flat treeland in the Para Ecological District. Mature tōtara, black beech and silver beech remained, and the reserve holds the nationally endangered yellow mistletoe, Alepis flavida.
Restoration planting began in 2003. Council records about 15,000 ecosourced seedlings planted by school children, the community, staff and contractors. A management plan was completed in 2006 with the QEII National Trust, and the reserve was placed under a QEII covenant.
The council’s restoration note was written while the understorey was still establishing, and it expected public access along a circular track to be promoted only once plantings had taken hold.
Later local accounts describe tracks and plant-identification signs. If you are planning a walk, check with Marlborough District Council first rather than assuming the track, parking or any camping arrangement is open.
Getting Around
Most people reach Koromiko by car or coach along State Highway 1. The drive from Picton is short. Blenheim is the next main town to the south. There is no passenger rail stop in the settlement.
Picton Airport, also called Picton Aerodrome, is on State Highway 1 at Koromiko. Sounds Air operates scheduled regional flights from the airport, including services across Cook Strait, and runs a shuttle between the airport and Picton township.
The airline advises that parking at the airport is paid. Check-in is at the main terminal building. This is a small regional airfield, not a substitute for Marlborough Airport at Woodbourne, which serves Blenheim.
For groceries, a bank, a library or a meal, Picton is the practical base. Koromiko itself is a place you pass through, fly into, or stop at for the church and the forest remnant, rather than a town centre in its own right.

Heritage New Zealand lists the place as private, with no public access recorded on the register. A local history says visitors have been able to look inside, but confirm before you enter.
What is Koromiko Forest Reserve?
It is a council-managed remnant of valley-flat forest, about four hectares, formerly a deer park. It is protected by a QEII covenant and is valued for old tōtara and beech, and for yellow mistletoe. Check with the council before you rely on track access.
What does the name Koromiko mean?
Koromiko is the Māori name for several native hebe shrubs. This guide has not confirmed that the settlement was formally named for the plant, or which iwi hold mana whenua here.
Is Koromiko a good base for Marlborough Sounds trips?
It works as a quiet stop or as the airport end of a Picton trip, not as a resort base. Picton has the shops, the harbour and the ferry, and it is a short drive north. Blenheim and the Wairau vineyards are to the south on State Highway 1.
