Guy Ngan: Data General, 1984

Artist: Guy Ngan
Title: Data General
Medium: Stainless Steel with reflective adhesive
Dimensions: Unknown
Date: 1984
Original location: Data General entrance lobby, 76 Boulcott St (off Plimmer Steps), CBD, Te Whanganui-a-Tara Wellington
Architect: Unknown
Current location: Lost
Heritage status: None known.


Ngan’s Data General mural extended along the corridors of a commercial building in central Wellington. Somewhat optically challenging as an artwork, rectangles of 3M reflective adhesive dance up and down the walls, punctuated by stainless steel strips. Horizontal and vertical lines collide, enhanced by fluorescent lighting strips on a reflective ceiling. Ngan’s idea was to bring in some light to an otherwise dark entrance way.

Ngan would later experiment with reflective surfaces in his mural for the National Bank in Hamilton.

Heritage status: None known


Having already mastered a range of paint, wood, concrete, and metal media, Guy Ngan elected, in the early 1970s, to turn his artistic hand to a new material: plastic. Wainuomata Shopping Mall became the home of his only known public sculpture in acrylic. 

In 1972, a designscape article recorded Ngan as considering himself to be ‘Playing around with plastics’, stating that he was not completely satisfied with the results.

Guy Ngan: BNZ Onehunga East, 1977

Artist: Guy Ngan
Title: Untitled
Medium: Paint on wood
Dimensions: 27.43m x 1.22m (90ft x 4ft)
Date: 1977
Original location: Bank of New Zealand, Onehunga East Branch, 146 Neilson St (cnr of Victoria), Onehunga, Tāmaki Makaurau Auckland
Architect: Ron Sang
Current location: Missing
Heritage status: No known protection


This striking frieze spanned two large walls in the Bank of New Zealand’s Onehunga East branch, opened in 1977. Designed by Ron Sang, a December 1977 article in the BNZ’s Staff News magazine describes the décor of the space as featuring “a specially commissioned bright green carpet, brown and orange furniture and fittings and strong orange enamelled ducting of the air-conditioning system”. Ngan’s mural, painted on wooden panels, was likely to have been in keeping with this vibrant colour scheme.

Alongside Ngan’s mural, a number of other artworks were featured as part of the branch fitout including “two colourful smaller murals woven of wool, one by Guy Ngan’s wife, Jean, and the other by Wellington weaver, Jenny Hunt, of Days Bay”, and two pots by Doreen Blumhardt.

Guy Ngan created both a kahikatea carving and mural for a temporary BNZ branch on Queen St, which had been set up while the main branch was undergoing alterations. The carving was inspired by the Auckland landscape with its volcanic cones and craters. The mural consisted of at least four panels and was installed directly opposite the woodcarving.

Guy Ngan: Automobile Association House, 1971

Artist: Guy Ngan
Title: Unknown
Medium: Aluminium relief with integrated lighting system
Dimensions: Approx. 14.63m (48ft) in length and 46.45m² (500ft²) in area. Exact dimensions unknown
Date: 1971
Original location: Automobile Association House, 164-166 Willis St, Te Aro, Te Whanganui-a-Tara Wellington
Architect: TBC
Current location: Unknown
Heritage status: TBC


Cast locally by T & E Foundries, Ngan’s wall sculpture for Automobile Association House was 48ft (14.63m) long, weighed around 1000lbs (453.6kg), and was backlit at night by concealed lighting. The connected circles symbolised mechanised wheels, while the linear patterns portrayed a roading system. One passerby commented, “I don’t like modern art but that looks like bits of car parts.”

In April 2000 Ngan noted that the work had been “mutilated”, possibly as it had been cut down to accommodate a verandah which had been added to the facade of the building.

The current whereabouts of this work is unknown.

Guy Ngan: National Bank Thames, 1969

Artist: Guy Ngan
Title: Unknown
Medium: Wood and metal
Dimensions: Approx. 4870mm (16 ft) in length. Exact dimensions unknown
Date: 1969
Original location: National Bank Thames Branch, 601 Pollen St, Pārāwai Thames
Architect: TBC
Current location: Unknown
Heritage status: TBC


Originally installed in the Thames branch of the National Bank, a news article in the Thames & Peninsula Gazette on 24 August 1976 states that the mural was relocated to Morrinsville. A photograph of the Morrinsville National Bank branch in 1988 confirms this. A maquette of the mural gives a good sense of the overall design, suggesting the work consisted of two panels.
