Sanctuary Community Organic Garden

Sanctuary Community Organic Garden An organic community garden and food forest formerly based by the Unitec grounds, Mt Albert, Auckland. In June 2017 it became an Incorporated Society.

• The Sanctuary Mahi Whenua has been a Community Garden since 2011 in a partnership arrangement with UNITEC Institute of Technology. We have a blog at sanctuarygardendiary.blogspot.co.nz and website at sanctuaryunitec.garden. There are some 60 members and their families involved, It is an entirely volunteer community garden with a waiting list of families wishing to join. Sustainable, spray-free,

organic growing principles are followed. In addition to growing mainstream crops, less well known crops are encouraged, such as peans and yacon, as well as heritage varieties.

• The site has been gardened since pre-European times. Some 12 Maori gardening implements were found in the cultivated area in 2007, and one is now displayed in the floor at the Unitec marae. When the site was an asylum (Oakley/Carrington Hospital) the gardens provided food for both staff and patients. When the area was purchased by Unitec, it became a Certified Organic teaching garden for horticulture. The food forest was established with nursery trees in 1999–2000 from an open grass site, followed by a mixture of subtropical and temperate fruit trees. The food forest is now being redeveloped.

• The cultivated area is about 1700 square metres, divided into communal and individual plots. The total area of the Sanctuary is about 7000 square metres — the cultivated area, food forest, headland shelter, composting area, swale, shed, and compound (with tunnel house, greenhouse, and hardening-off area).

• There are a number of significant trees in the Sanctuary, including some from the Three Kings Islands and similar offshore locations: these originated mainly from duplicates at the Mt Albert Research Centre.

• In addition to providing organic vegetables and fruit for the plotholder families, the Sanctuary reaches out to the wider community in a variety of ways:
o Unitec Department of Natural Sciences harvest the spray-free grass and weeds (e.g., dock) to feed the animals looked after by students studying towards Certificates in Animal Care. Hence there are “rough areas” around the Sanctuary perimeter. o Auckland Zoo primates receive most weeks a crate containing spinach and native puha (Sonchus kirkii). The native puha is endangered in the wild, and is now very restricted in its range (mainly where it cannot be reached by grazing animals). Occasionally prunings from our Coprosma trees are provided as well as seeding red amaranth. o The Sanctuary supports the Monte Cecilia Housing Trust, by donations of either food or money. o Some produce from communal areas is sold at the community table at the Grey Lynn Farmers Market (Grey Lynn Community Centre, Richmond Road, Sunday mornings) to help defray some of the ongoing running and maintenance costs of the Sanctuary. o Plants in the food forest, headland shelter, and swale provide year-round food and shelter for insects and birds. Sunflower seeds and red amaranth provide food for birds of the areas (mainly finches) when mature, and in return their guano helps fertilise the garden. Note: VERA, the Vertical Composting Unit by the shed, was an experimental unit built for Unitec that is no longer operational.

Flashback to 11 years ago, early September 2014. The community broad beans (Vicia fabae) at the Sanctuary Mahi Whenua were flowering and attracting many bumblebees (Bombus terrestris)(https://sanctuarygardendiary.blogspot.com/2014/09/). Later this communal space became the rainbow garden area. Photograph by Jeannie Hayden.

In mid-July someone wrote "Save da trees!" on the 30,000 litre water storage tank at the Sanctuary Mahi Whenua. We all appreciated the sentiment expressed, but knew that soon all but a few trees were due to be destroyed. The words were still on the tank when it was transported away 5 days later (see 24 July post). Photograph by Bev Crosby.

Around 80 bags of highly productive Sanctuary Mahi Whenua soil were collected on our final day of access. This will be available later for our use elsewhere. The report on our soils by Manaaki Whenua Landcare Research in March 2025 reported that there were high concentrations of plant-available phosphorus (luxury levels), and our soils did a fabulous job of storing and supplying water (a sponge).

One of the last tasks in vacating the Sanctuary Mahi Whenua last week was to package some 50 bags of ready-to-use compost. The hot compost cake in this bin was started just 3-4 months earlier from a wide range of green vegetation and woody material from the Sanctuary.

Friday's action by Aaron of Aarons Contracting Ltd to uplift the Pennantia baylesiana at the Sanctuary Mahi Whenua so it could transported for rehoming at the Mt Albert Research Centre. Many vines of the Three Kings Island climber (Tecomanthe speciosa) growing up and around the Queensland kauri (Agathis robusta) close to the Pennantia had to be cut back beforehand so the spade on the back left could be engaged correctly.

Aaron of Aarons Contracting Ltd was also able to uplift the lancewood or horoeka tree (Pseudopanax crassifolius) growing in the swale at the Sanctuary Mahi Whenua on Friday. This tree has been showing its adult form for some years now. This native species has a juvenile stage with long, serrated leaves lasting 15-20 years. The species is found throughout New Zealand from sea level up to about 750 m.

Allan Woolf (Principal Scientist, Postharvest Fresh Foods BSI, Mt Albert Research Centre) with Aaron of Aarons Contracting Ltd after the successful rehoming yesterday of the Sanctuary Mahi Whenua Three Kings kaikōmako (Pennantia baylesiana) tree. Allan worked quickly to get agreement with the Bioeconomy Science Institute that this rehoming could occur. Our tree is now "back home", as it was raised here as a sapling before being planted in the food forest at the Sanctuary Mahi Whenua. Photograph sent by Allan Woolf.

Aarons Contracting Ltd uplifted and rehomed this Pennantia baylesiana from the Sanctuary Mahi Whenua to the Mt Albert Research Centre today. Many vines of the Three Kings Island climber (Tecomanthe speciosa) growing up and around the Queensland kauri (Agathis robusta) close to the Pennantia had to be cut back so the spade on the back left could be engaged correctly. Thank you Aaron for your expertise, resulting in the rehoming of one of New Zealand's rarest trees.

About to happen today, Aarons Contracting Ltd uplifting and rehoming Pennantia baylesiana from the Sanctuary Mahi Whenua to the Mt Albert Research Centre. Some vines of the Three Kings Island climber (Tecomanthe speciosa) will need to be disentangled.

Tomorrows transplant mission:

Saving one of NZ’s rarest trees.

This Three Kings kaikōmako, (Pennantia baylisiana) is hidden deep in the back of the Unitec Community Sanctuary Garden which is due to be cleared out.

Probably for a carpark.

Last minute call for help! Teed up to be shifted over to the Plant and Food Research facility, before the site becomes inaccessible.

A background on this species:

The Three Kings kaikōmako is endemic to Manawatāwhi/Three Kings Islands, around 55 km northwest of Cape Reinga. At the time of its discovery in 1945 just one female plant remained, and it grew on a scree slope inaccessible to browsing goats. It proved difficult to propagate, and its conservation status is "Critically Endangered".

And stayed tuned for a couple of other gems in this sanctuary that I really hope the officials let us grab!
