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.
Taonga
Many native species hold significant meaning and relationships with mana whenua of Ahuriri. There are several key indicator species such as Tohorā and Kororā.
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.
QUANTITATIVE
Is the population of Kororā increasing?
Health
Method of Testing
Surveys undertaken through the 6 Wharf project. The Kororā dog indicates the number of nesting sites in the Port along Hardinge Rd and in the Inner harbour.
Method of Scoring
0 = Not seen or heard at all.
1-3 = Decrease in kororā by >50%.
4-6 = Decrease in Kororā between 50 and 45%.
7-9 = Population stable (increase or decrease by up to 10%).
10 = Population increase by 10%.
QUANTITATIVE
How is the health of the Kororā?
Health
Method for Testing
Surveys undertaken through the 6 Wharf project. Utilise Kororā health index.
Method for Scoring
1-3 = Decrease in kororā health by 50+%.
4-6 = Decrease in kororā health 50-40%.
7-9 = Kororā health same (increase or decrease by up to 10%).
10 = Population increase by 10%.
QUANTITATIVE
Is the habitat area for Kororā increasing or decreasing?
Health
Method for Testing
Survey inner harbour area, draw polygons using mapping system to determine area.
Method for Scoring
0 = Decrease in kororā habitat by > 20%.
1-3 = Decrease in kororā habitat by 10-20%.
4-6 = Decrease in kororā habitat 2-10%.
7-9 = Kororā habitat the same (increase or decrease by 1%).
10 = Habitat increase by 5%.
QUANTITATIVE
Is the population of Kekeno increasing or decreasing?
Health
Method for Testing
Surveys undertaken through the 6 Wharf project.
Method for Scoring
0 = Decrease in Kekeno by >75%.
1-3 = Decrease in Kekeno by >50%.
4-6 = Decrease in Kekeno between 50 and 45%.
7-9 = Population stable (increase or decrease by up to 10%).
10 = Population increase by 10%.
QUANTITATIVE
Is the habitat area for Kekeno increasing or decreasing?
Health
Method for Testing
Survey undertaken through the 6Wharf project.
Method for Scoring
0 = Decrease in kekeno habitat by > 20%.
1-3 = Decrease in kekeno habitat by 10-20%.
4-6 = Decrease in kekeno habitat 2-10%.
7-9 = kekeno habitat the same (increase or decrease by 1%).
10 = Habitat increase by 5%.
QUANTITATIVE
What is the frequency of sightings within the Ahuriri marine area?
Health
Method for Testing

Method for Scoring
0 = Decrease in Aihe by > 75%.
1-3 = Decrease in Aihe by >50%.
4-6 = Decrease in Aihe between 50 and 45%.
7-9 = Sightings stable (increase or decrease by up to 10%).
10 = Population increase by 10%.
