Rockburn

Rockburn began as the side project of one of New Zealand's most senior heart surgeons. In 1991, Dr Richard (Dick) Bunton, who has led the Department of Cardiothoracic Surgery at Dunedin Hospital since 1995, planted a 3-hectare hobby vineyard on the northern shore of Lake Hayes near Arrowtown, drawn by the new wave of Central Otago Pinot Noir then taking shape. The hobby quickly outgrew its bounds. In 1992 Bunton developed a more serious 9-hectare site on Gibbston Back Road, the road that runs along the Kawarau Gorge above the original wave of Gibbston plantings, and in 1998 released the first commercial wines under the Hayes Lake label. By 2002 the brand had been renamed Rockburn, a name drawn from the rugged, rock-strewn, burn-scarred Otago landscape that better captured the schist-driven Central Otago identity. The Lake Hayes site was eventually retired and the Gibbston Back Road vineyard became the founding site of the producer. In 1999, Chris James joined the business and Rockburn purchased the 33-hectare Parkburn block on Lake Dunstan, giving the brand the two-vineyard structure it still works with today.

• 1999: Chris James joins the business; Rockburn purchases the 33-hectare Parkburn vineyard on Lake Dunstan in the Cromwell Basin
• 2002: Brand renamed Rockburn to reflect the rugged, rock-strewn Central Otago landscape

Rockburn works with two vineyard sites that together cover much of Central Otago's climatic range. The original 9-hectare Gibbston block (renamed the Dick Bunton Vineyard on Bunton's retirement) sits on Gibbston Back Road in the Kawarau Gorge, on the cooler, higher-elevation side of the region. Gibbston is the coolest and latest-ripening of Central Otago's subregions, sheltered by the Crown Range and Remarkables, and the wines from this site are typically perfumed, fine-boned, and structurally driven, with violet lift and red-fruited core. The 33-hectare Parkburn vineyard, planted from 1999 on a terrace at Lowburn on the western shore of Lake Dunstan, sits in the warmer, drier Cromwell Basin beneath the Pisa Range. This is heart-of-Central-Otago country: dramatic diurnal swings, low rainfall, free-draining glacial outwash soils, and longer ripening hang time. The two sites in tandem give the winemaking team the building blocks for elegance from Gibbston and concentration from Parkburn, and the choice of which fruit goes where in the blend or which barrels make the single-vineyard cuvees defines the house style. In 2016 the new winery at Ripponvale Road in Cromwell was chosen specifically because it sits roughly equidistant between the two vineyards on the route between them.

• Dick Bunton Vineyard (formerly Gibbston Back Road): 9 hectares on Gibbston Back Road in the Kawarau Gorge; cool, late-ripening Gibbston subregion; Pinot Noir and Pinot Gris on schist-derived loess soils
• Parkburn Vineyard: 33 hectares on a terrace at Lowburn on the western shore of Lake Dunstan; warmer Cromwell Basin climate beneath the Pisa Range, with deep glacial outwash gravels and significant diurnal variation
• Gibbston typically delivers perfume, violet lift, and finer structure; Parkburn delivers depth, riper red and black fruit, and weight; the two sites together cover much of Central Otago's stylistic range
• 2016: New Rockburn winery completed at Ripponvale Road, Cromwell, chosen for its central location between the two vineyards; on-site cellar door opened December 2025

Malcolm Rees-Francis has been Rockburn's winemaker since 2005, joining after a formative stint as assistant winemaker to Blair Walters at Felton Road, the producer that did more than any other to define modern Bannockburn Pinot Noir. He completed his 20th Rockburn vintage in 2025 and has been the single defining hand on the house style for two decades. The approach is minimal-intervention but not dogmatic. Pinot Noir blocks are picked on site and parcel character rather than by sugar number, with most fruit destemmed and a meaningful but variable whole-bunch component (typically 10 to 30 percent) used to add structure and aromatic complexity. Fermentations run on indigenous yeasts in open-top fermenters with extended cold soaks and gentle plunging, and pressings move into French oak barriques with a measured new-oak percentage that varies by tier (lower on the regular Pinot Noir, higher on Seven Barrels, Eleven Barrels, Twelve Barrels, and The Art). The aromatic whites take a similarly hands-off path: cool-fermented Sauvignon Blanc and Pinot Gris in stainless steel for varietal purity, the Fumé Blanc and Chardonnay with measured barrel work, and the Riesling in a precise, off-dry to dry Central Otago style.

• Malcolm Rees-Francis: winemaker since 2005, 20th vintage completed 2025; previously assistant winemaker to Blair Walters at Felton Road in Bannockburn
• Pinot Noir: hand-picked by parcel; destemmed with a typical 10-30% whole-bunch component depending on cuvee; indigenous yeast fermentation in open-top vessels with extended cold soak
• French oak barrique aging with new-oak percentage scaled by tier: lower on regular Rockburn Pinot Noir, higher on Seven Barrels, Eleven Barrels, Twelve Barrels, and The Art
• Whites: stainless steel for varietal-purity Sauvignon Blanc and Pinot Gris; barrel work on Fumé Blanc and Chardonnay; precise off-dry to dry style for Riesling

Rockburn's Pinot Noir lineup is one of the more complete in Central Otago, scaling from a sub-$30 entry point to single-site reserves that compete at the regional pinnacle. The Devil's Staircase Pinot Noir is the entry tier, named after the winding road south from Queenstown along Lake Wakatipu, and is built as a fresh, bright introduction to Central Otago Pinot Noir for everyday drinking. The regular Rockburn Central Otago Pinot Noir is the workhorse blend across both vineyards, offering the house signature of red-cherry fruit, gentle whole-bunch spice, and balanced oak. Above it sit the limited barrel-selection wines that are the producer's calling card. Seven Barrels Pinot Noir, drawn from the Dick Bunton Vineyard in Gibbston, is a selection of just seven barrels each vintage that most clearly express the cool-climate perfume and structure of the Gibbston subregion. Eleven Barrels Pinot Noir, sourced from the Parkburn vineyard, is the Cromwell Basin counterpart with greater depth, darker fruit, and richer weight. The Twelve Barrels Gibbston Vineyard Pinot Noir sits in the same Gibbston single-site family with a slightly larger production footprint. The top of the tree is The Art Pinot Noir, made from a single vineyard high in the Dunstan foothills outside Rockburn's home blocks, given to Malcolm Rees-Francis to interpret with maximum winemaking expression: significant whole-bunch, careful new oak, and extended elevage. The Art is consistently scored among Central Otago's elite Pinot Noirs, with the 2021 release rated 95 points by Cameron Douglas MS.

• Devil's Staircase Pinot Noir: entry tier; named after the winding road from Queenstown along Lake Wakatipu; fresh, bright, accessible style
• Rockburn Central Otago Pinot Noir: estate blend across both vineyards; house signature of red cherry, gentle whole-bunch spice, and balanced oak; the wine that won Champion Pinot Noir and Champion Wine of the Show at the 2019 New Zealand International Wine Show (with the 2017 vintage)
• Seven Barrels (Gibbston): just seven barrels selected each vintage from the Dick Bunton Vineyard; perfumed, structured, cool-climate Gibbston expression
• Eleven Barrels (Parkburn): Cromwell Basin counterpart from the Parkburn vineyard; darker fruit, more weight, broader structure
• Twelve Barrels Gibbston Vineyard: larger-production Gibbston single-site Pinot Noir with the same village identity as Seven Barrels
• The Art Pinot Noir: premium single-vineyard release from a Dunstan foothills site; whole-bunch driven, extended oak elevage; 2021 vintage rated 95 points by Cameron Douglas MS

Rockburn's white wine program is built around aromatic precision and the natural acidity of Central Otago's continental climate. The Riesling is the calling card of the white range, made in an off-dry to dry style with the citrus precision and high natural acid that Central Otago does as well as anywhere in the southern hemisphere. The Pinot Gris is fermented in stainless steel for pear, white-peach, and ginger-spice purity. The Sauvignon Blanc shows a tauter, more mineral profile than Marlborough's tropical norm, reflecting the higher altitude and stonier soils of Central Otago, while the Fumé Blanc adds careful French oak work for a smoky, more textural style. The Chardonnay is barrel-fermented with measured new oak. Outside the core range, the Stolen Kiss Rose is made from Pinot Noir saignee juice 'stolen' from the red wine fermenters, giving the wine its name; it is a dry, structured Central Otago rose with redcurrant and watermelon fruit and the cellar door's most consistent summer seller. Crimson Peak is the second label, a more affordable range that uses fruit not destined for the main tier and gives the cellar door an entry point for international visitors.

• Riesling: off-dry to dry style with citrus precision and Central Otago natural acid; one of the calling-card aromatic whites in the lineup
• Pinot Gris: stainless steel fermentation; pear, white peach, and ginger spice profile
• Sauvignon Blanc and Fume Blanc: mineral-driven Central Otago Sauvignon (more taut than the Marlborough norm) in stainless steel and the Fume version with measured French oak work
• Chardonnay: barrel-fermented with measured new oak; ripe stone fruit, citrus, and gentle toast
• Stolen Kiss Rose: dry Pinot Noir saignee rose 'stolen' from red fermenters; redcurrant and watermelon fruit, the cellar door's signature summer wine
• Crimson Peak: second-label entry range using fruit not destined for the main Rockburn tier

Rockburn has spent much of the last two decades consolidating its position as one of Central Otago's most widely distributed and consistently rated mid-to-upper-tier producers. The 2017 vintage of the regular Rockburn Central Otago Pinot Noir won both Champion Pinot Noir and Champion Wine of the Show at the 2019 New Zealand International Wine Show, the country's largest wine competition by entry numbers. The Art Pinot Noir has been a regular high scorer with critics including Cameron Douglas MS and Raymond Chan, and the Seven Barrels and Eleven Barrels selections are among the more sought-after limited-release Pinot Noirs in the Central Otago portfolio. The producer is now in its first major generational transition. In 2024, founding director Dick Bunton was awarded the ONZM in the New Year's Honours for services to cardiothoracic surgery, and at the same time announced his pending retirement from Rockburn, selling his stake to the remaining founding directors Chris James and Paul Halford. The James and Halford families now hold the company privately, and the original Gibbston Back Road vineyard has been renamed the Dick Bunton Vineyard in his honour, with the Seven Barrels Pinot Noir now bottled with the Dick Bunton Vineyard designation. The cellar door at the Ripponvale Road winery opened to the public in December 2025, operating Tuesday to Saturday by appointment.
