National Radiators introduced the:

  • Single Row CT Core

  • 2 Row x 10mm Tube Pitch CT Cores
  • 3 Row x 12mm Tube Pitch CT Cores
  • 4 Row x 12mm Tube Ptich CT Cores

Followed a few years later by:

  • 3 Row x 10mm Tube Pitch CT Cores
  • 4 Row x 100 Tube Pitch CT Cores

Which took the core range and the core efficiency to the next level.

1985: Lean manufacturing process

In late 1985 Alf King took over as General Manager. He initiated the lean manufacturing process making National Radiators a ‘Just in time Supplier’ to the ten Car Assembly Plants in New Zealand.

At this stage the annual production was:

  • 75,000 OE Assemblies – 100 different models.
  • 75,000 Replacement Cores.
  • 120,000 Pressure Caps.
  • 150 Employees in Wellington, Dunedin and Boston Road Auckland.
  • First Fax Machine.

1985-1988:

During this period the combination of:

Reduced tariff protection on motor vehicles, the move to plastic tank radiators and the predicted lower number of vehicles of assembled in NZ were the reasons behind the decision to close the OE plant in Wellington by April 1988.

In mid 1987 National Radiators acquired Radiator Industries and amalgamated the two companies into one aftermarket plant at the current site in Walls Road in April 1988.

The National Radiators Boston Road Branch in Auckland was closed at the same time and the repair shop was moved to the Walls Road plant.

Bulk Stock Sale of Components.

1988-mid 1990:

In the late 1980s until 1998 we witnessed the largest changes in the New Zealand automotive industry history.

Some of the car assembly plants closed down and the remaining plants started to import CBUs (completely build up cars).

The Government then also opened the door for used car imports, which amounted to more than 100,000 used vehicles being imported every year. By 1998 all the car assembly plants were closed.

By now the New Zealand car park consisted of a very large range of models and to service the replacement radiators for all these models was a great but rewarding challenge.

During the first few years the Walls Road Plant manufactured 70,000 replacement cores and sold up to 18,000 plastic tanks per annum.

Mid 1990-2004:

However, during the mid 1990’s the Japanese used parts warehouses started up and became the largest competitor to National Radiators competing with second hand radiators.

Some of the largest insurance companies used second hand radiators for crash repairs.

In order to stay competitive and profitable National Radiators had to reduce cost and the staff level was gradually reduced.

As part of the cost reduction plan we closed the Dunedin Branch and moved the vintage core manufacturing equipment to Auckland.

mid 1990-2004

In 2001 another competitor entered New Zealand when Adrad opened a warehouse in Penrose only a short distance from our Walls Road Plant. Adrad was very aggressive in obtaining market share by offering Quality products at super competitive prices.

In 2003 our competitor Radev Radiators sold their manufacturing plant to Adrad, providing them with instant access to radiator core manufacturing in New Zealand.

2006: Adrad acquired the Natra Group
