FAR Review Update
The NZ Transport Agency reviewed the Financial Assistance Rates (FAR) provided by central
government for land transport activities. FAR determines how the costs are split between
local authorities and the National Land Transport Fund in providing and maintaining the
road network. On the bright side the Transport Agency has decided to fund at the co-

Waiwhakaiho Catchment for municipal water supply purposes.

this report also assigns a rating as to each Company’s environmental and administrative performance during
the period under review. The rating categories are high, good, improvement required and poor for both
environmental and administrative performance. The interpretations for these ratings are found in
Appendix II.
For reference, in the 2021-2022 year, consent holders were found to achieve a high level of environmental

categorised, 3 (14%) were rated ‘improvement required’ and 18 (86%)
‘high’. During the year under review there were two incidents associated with the Whareroa
site (one regarding an exceedance of stormwater BOD resulting in the issuing of an
abatement notice, and one due to excessive dust during construction).
Water abstraction from the Tawhiti Stream and from the Tangahoe River were in accordance
with consent conditions.
The volume of wastewater discharged from the site complied with conditions
However, taking into
account the influence of suspended sediment in this reservoir, and the moderately low
chlorophyll levels, the classification is more appropriately mesotrophic. Previous trending of
these water quality data over time found a very slow rate of increase in trophic level. An
update of the trend report (for the period 1990-2015) has confirmed this very slow,
insignificant rate of increase in trophic level. This also confirmed that the lake would be
classified as mesotrophic in
detrimental effects were found at the time of the November survey. At the time of the March
survey the results suggested poor preceding water quality that may be indicative of adverse effects
associated with the landfill leachate.
Air quality monitoring showed that there were no significant adverse effects in relation to suspended
particulates, dust deposition rates or odour beyond the site boundary.
An enclosed gas flare system was installed for air quality control during the 2017-2018
discussing the various details of the performance and extent of compliance by MASL, this report
also assigns them a rating for their environmental and administrative performance during the period under
review.
Environmental performance is concerned with actual or likely effects on the receiving environment from the
activities during the monitoring year. Administrative performance is concerned with MASL’s approach to
demonstrating consent compliance in site operations and management including the
ultimately, through the refinement of methods and
considered responsible resource utilisation, to move closer to achieving sustainable
development of the region’s resources.
1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by
the Company, this report also assigns them a rating for their environmental and
administrative performance during the period under review.
