Finger Jointed Timber

Finger Jointing From Quality New Zealand Pine


Finger jointed products are created from quality New Zealand pine from which defects, such as knots, have been removed. Finger joints are precisely cut into the pieces of timber, and each joint is then glued in place. This creates a product with stability and strength superior to the original pieces of timber.


Finger jointing is used for structural products such as laminated beams, and also for appearance products, such as balustrades, fascia and weatherboards.

The products created from our finger jointed timber are easy to handle. They have excellent machining qualities, and a high quality finish can be achieved.

Our Specialised Finger Jointing Process


Niagara is proud to be one of New Zealand’s leading timber processors. With over 85 years in the timber industry, and 30 years manufacturing Niagara is the trusted name in finger jointed products in New Zealand and overseas.

In 2018 Niagara completed the install of a new state of the art remanufacturing plant at the Kennington Site. Designed with high multi-functionality and flexibility in mind, the finger jointing line encompasses many production processes within one single system.

From start to finish, the line takes in raw material and produces two types of finished, flawless, finger jointed products (horizontal and vertical).

Rough sawn kiln dried timber coming into the remanufacturing plant is machined through a Ledinek planer to give a smooth uniform finish ready for defecting and finger jointing.

The timber is then scanned through a Goldeneye 500 at up to 220 metres per minute. The Goldeneye 500 Multi-Sensor Scanner precisely recognises and localises wood defects selecting only the best material for finger jointing.


This information is then communicated to three System TM Opti-Kap saws that remove all defects and knots producing a clear timber shook ready for fingerjointing. 

Niagara produces both vertical and horizontal finger joints, giving the flexibility to offer either a face-to-face or edge-to-edge joint in lengths ranging from 1.8 to 7.2 metres. 

The range of products produced is large and varied and includes door jambs, window reveals (liners), mouldings, laminated posts and beams, fascia, trim boards and edge glued wide boards

Throughout the manufacturing process there are documented quality assurance systems to guarantee customers only receive product that meets their specification. Niagara’s finger jointing operation is certified and independently audited to AS/NZS 1491 and AS 5068, which is yet another way Niagara guarantees customers’ expectations will always be met.
