Health Spectrum

The health ratings displayed on this page is an example only, the heath ratings will be updated when monitoring is completed at the end of 2021.
Mahinga kai
Traditional food resources are important indicators of marine ecosystem health. Species like kuku (green-lipped mussels) and koura (crayfish) are key indicator species for mana whenua of Ahuriri.
Below are the results of each of the Tohu Whāiti associated with this Tohu Matua. These Tohu Whāiti collectively inform the overall health of this Tohu Matua.
For each Tohu Whāiti we score qualitative and quantitative indicators called Pātai Inenga, we use these score to determine the health of each Tohu Whāiti. The ratings below are on a scale of 0 to 10, with 0 being very weak and 10 being very strong.
QUALITATIVE
In the past 12 months, have you gathered any kuku?
Health
QUANTITATIVE
Are the Kuku beds growing, shrinking or staying the same?
Health
Method of Testing
Hapū groups will be surveyed annually utilising the survey application.
Method of Scoring
Check box list of mahinga kai species includes: kuku, kōura, pāua, kina, pupu or pipi, ika, karengo, none of the above
Show subsequent questions for the mahinga kai species the respondent selected only.
QUANTITATIVE
Are the Kuku healthy? (growth, stress, contaminants)
Health
Method of Testing
Reference video clip for detailed monitoring methodology. Annual deployment of cages during dredging. Routine collection of kuku from same spot to assess patterns in condition over time.
Method of Scoring
0 = Decline in weight and contaminated.
1-3 = 10-30% increase in condition. >6 e.coli/entero present.
4-6 = 40-60% increase in condition. 2-6 e.coli/entero present.
7-9 = 70-90% increase in condition, not present e.coli/entero.
10 = 100% increase in condition. Not present e.coli/entero.
QUANTITATIVE
Is the population of Kuku breeding well? (Recruitment/spat abundance)
Health
Method of Testing
Reference video clip for detailed monitoring methodology. Deployment of spat collectors monthly over spawning season.
Method of Scoring
0 = Decline or no recruitment.
1-3 = 10-30% increase in recruitment.
4-6 = 40-60% increase in recruitment.
7-9 = 70-90% increase in recruitment.
10 = 100% increase in recruitment.
QUALITATIVE

If yes ask:
How easy or difficult is it to gather a feed of pipi from these spots?
0 = Very difficult
10 = Very easy
How easy or difficult is it to gather a feed of pūpū from these spots?
