Tuapaka Farm , Pāmu Tuapeka

Objectives

• To provide a facility for quality research, teaching and extension in sheep and beef farming.
• To be managed as a profitable commercial sheep and beef farm.
• To provide a link between the university and agribusiness.

Farm features

About the farm

The original 420 hectare farm was acquired in 1938, with a further 56.5 ha added in 1971. In 1983, Tuapaka's 420 hectares were divided into 2 blocks so that better commercial use could be made of the farm:

• a 111-hectare unit of predominantly flat ground, and
• a hill unit of 365 hectares.

Initially following this subdivision it was decided to run bulls from weaners to 18 months on the smaller unit, with a sheep and bull beef system put into place on the larger unit.

Recently, management strategies have changed to better use the property and improve the farms ability to service research and teaching activities.

The property is subdivided into 85 paddocks which are made up of:

• flats: 31 paddocks ranging from 1.3 to 5.2 ha
• hill unit: 54 paddocks ranging from 1.2 to 12.8 ha.

Fences on both the flats and hill unit are conventional posts and battens with electric outriggers, plus some 3 wire permanent electric. A grass laneway system allows access to all paddocks on the flats.

Location and map

Area

476 hectares:

• 111 hectares flat block
• 365 hectares hill block

Effective area: 359 hectares (99 hectares flat block, 260 hectares hill block).

Altitude

100 – 360 metres above sea level.

Contour

Flat unit

Mostly flat with some rolling country.

Hill unit

Rolling to very steep hill country.

Noxious weeds

Gorse and California thistles.

Noxious animals

Possums and rabbits.

Soils

Flat block

Tokomaru Silt Loam and Ohakea Silt Loam (derived from wind-blown dust from riverbeds). The subsoil is compacted which causes the soil to be slow draining. Natural fertility is medium to high.

Hill block

Steepland soil related to Makara Steepland Soils derived from greywacke and slope deposits. Natural fertility is generally low to very low.

• Hilly and Steepland soils related to Halcombe hill and steepland soils – derived from loess, unconsolidated sediments and slope deposits. Natural fertility is very low.
• Shannon and Tuapaka series – derived from loess overlaying marine sands and have a naturally low fertility.
• Korokoro series – derived from loess and slope deposits overlying greywacke, these soils are generally free draining and have a low natural fertility.

Climate

Climate data for Aokautere, the nearest Council monitor to the farm.

Tuapaka Farm experiences 1,100 mm of average annual rainfall. Summer is mainly dry. Prevailing winds are westerlies and south easterlies.

Water supply

Water sourced from a bore with water being pumped to reservoirs on the hills and gravity-fed to most paddocks.

Farm buildings

The homestead was extensively upgraded in 2018. The Shepherd General’s house is tired and is programmed for an upgrade. The third empty dwelling is beyond refurbishment.

Five-stand wool shed and covered yard complex with a 1,500-ewe capacity. Two sets of satellite yards. One main set of cattle yards (near the wool shed) with 5 main pens with concrete floor crush to race and weighing platform (electronic scales), head bail and spray dip. Another satellite set of yards near the south-western farm boundary.

Staff

One permanent staff and casual staff as required.

Pastures and forestry

The flats are on a 5 year rotation of hybrid ryegrass/chicory/white clover species. For the hill unit, typical hill country pastures dominate consisting of browntop, crested dogstail with perennial ryegrass and white clover.

Forestry

As part of the Waka Kotahi construction of the new Ashhurst/Woodville expressway, 16.43ha of riparian and wetland areas were planted in the winter 2021 to offset resulting environmental damage. In conjunction with this programme Tuapaka management has identified a further 9.4ha which has been retired and earmarked for future biodiversity planting.

Cover

As at 1 July 2025.

Total cover 472.41 hectares.

Livestock policies

Sheep

Approximately 1,400 breeding ewes, slightly less than 560 replacement ewe hoggets and 24 rams are carried on Tuapaka.

Replacements are bred on farm. In the past all MA Ewes were mated to a FE resistant Romney maternal sire. In 2025 shedding rams have been introduced. Heavier lambs are transferred to Keebles for finishing; lighter lambs are sold store.

Around 260 MA ewes are transferred to Keebles annually.

When seasonal conditions are favourable Ewe hoggets are mated early May to a Terminal sire.

Key strategies to improve the performance of the flock are as follows:

• Continued pasture improvement involving a 5-year rotation of chicory clover on the flats (around 100ha).
• A focus on all year-round nutrition of the ewe flock and hogget growth rates with an objective of lifting per head performances. Specifically:

Heavier ewes at tupping – MAE at 65kg. 2ths at 63kg. There is now an emphasis in managing fecundity to limit triplet births and raising lamb survival and weaning weights.

• Focus on growing hoggets from weaning. Treat these as a finishing animal.
• Lowering the ewe death rate to provide more cull ewes for sale and more selection pressure in the flock.

Production and future targets

Cattle

Tuapaka has recently bred up an Angus breeding herd. The herd comprises 116 breeding cows (91 Angus breeding cows, 25 in-calf Angus heifers) and replacements. Also grazed are six Angus bulls, 90 Angus calves.

In 2024 Tuapaka enrolled in the Beef & Lamb Genetics Informing NZ Beef (INZB) program.

The objectives of the programme are to:

• develop a beef genetic evaluation system that includes traits that are important to New Zealand beef farmers and supports a sustainable beef farming industry.
• create easy-to-use tools that enable data to be efficiently collected, managed, analysed and used by farmers to make profitable decisions for their operation.
• create a new approach to extension design with the goal of increasing farmer engagement across the industry.

Key strategies to improve cattle performance are:

• Target winter growth rates of over 0.5kg/day for June and July.
• Kill over 100% of steers & 70% trade heifers before the second winter
• Weaning weight equivalent to 50% of dam winter weight.

Production and future targets

Fertiliser

Soil tests are undertaken biennially on pre-determined transect lines.

Fertiliser applications are then planned in conjunction with the Fertiliser rep using Overseer with objective of achieving economic optimum applications.

The following table shows the average soil test readings on Tuapaka since the regular testing regime was established in 1988.

Flat unit

Hill unit

The 2025 fertiliser programme which reflects current soil test data is as follows:

Flats:

• Autumn: 175kg/ha Sulphur Super + Selenium (0-15-0-26)
• Spring: 80kg/ha Ammo31 PRO (25-0-0-11)

New Grass:

• Autumn: 200kg/ha Cropmaster15 (30-20-20-15)
• Spring: 200kg/ha Cropmaster15 (30-20-20-15)

Research

We have 3 research projects currently underway at Tuapaka Farm.

Stream nitrate concentrations

Monitoring stream nitrate concentrations leaving an 85ha catchment on farm via the Main weir using a high frequency nitrate sensor in order to develop strategies to enhance nitrate attenuation in these features.

Water quality impact – sheep accessing natural waterways

Monitoring the behaviour and impact of sheep accessing natural waterways in spring, summer, autumn and impact on water quality.

Edible native plants

Edible native plant species in North Island hill country.

History

The original 420 hectare farm was acquired in 1938, with a further 56.5 ha added in 1971. Massey leased the land for approximately 10 years (1938-1948) and following Crown ownership acquired freehold title in 2018. Tuapaka is administered and managed by Massey Ag & Hort Enterprises.
