New Zealand’s dairy industry

New Zealand dairy industry

Environmental reports and main stream media are often critical of different aspects of the New Zealand dairy industry. Here I summarise them together in one graphic. View at higher resolution by clicking on the image below.

Map of dog prohibited area at Tahuna Torea Nature Reserve

Like many locals I regularly ask people to not walk their dog at Tahuna Torea Nature Reserve. Sometimes dog walkers push back and say they are allowed to walk their dogs on the beach or around the top of the track. To make it clear here is the wording from the Auckland Council website:

“Dogs are prohibited at all times in Tahuna Torea Nature Reserve. This covers all park areas and associated beach and foreshore areas from the public walkway between 24 and 26 Vista Cresent to its boundary on West Tamaki and Tahaki Roads.”

Here is a map to visually explain the area.

To map the “beach and foreshore areas”, I projected the boundaries perpendicular to the starting points on land, down to the low tide line. Mean Low Water Springs (MLWS) has been visually estimated.

Update March 2024

Roberta Reserve also excludes dogs on the foreshore and playground. There is an exemption for the area in the water of the stream mouth seaward side of the bridge on Roberta Reserve.

LegaSea’s displacement argument

LegaSea are asking their supporters to object to the Hauraki Gulf Marine Protection Bill due to concern’s about displacement.

“We do not believe the proposed protection measures go far enough to restore fish abundance and biodiversity in the Hauraki Gulf. Marine protection and fisheries management controls need to go hand-in-hand, otherwise all we will do is shift current fishing effort into our neighbour’s waters. We want 100% of the Hauraki Gulf seafloor protected from destructive, mobile fishing methods including bottom trawling, Danish seining and dredging. And, we want Ahu Moana, a joint iwi/hapū and community driven solution to resolve local depletion issues.” (Full email published here).

If we forget about the many non-fishing benefits of marine protection, then also forget about the fisheries benefits of marine protection (nursery and spillover) then forget about the fisheries plan which aims to rebuild stocks including Ahua Moana we are left with LegSea’s naïve argument over a limited amount of fish. Does it stand up?

No, the recreational losses for all species fished in the HPAs total 293 tonnes, the proposed commercial reductions from the corridors will total between 632-1017 tonnes.

Update January 2024. Marine scientists at the University of Auckland have done some excellent work looking at the displacement argument.

Math + references:

Calculating the weight of recreational catch lost to HPAs

Recreational fishers harvested 2,068 tonnes of snapper from the HGMP in 2017/18 fishing year. 9.58% of the recreational fishing effort is in the proposed High Protection Areas. The HPAs will reduce recreational fisheries catch of snapper by 198 tonnes. 

Recreational fishers harvested 517 tonnes of kahawai from the HGMP in 2017/18 fishing year. 9.58% of the recreational fishing effort is in the proposed High Protection Areas. The HPAs will reduce recreational fisheries catch of kahawai by 50 tonnes.

These two species represent 82% of the fish (by weight) caught in the Gulf in the 2017/18 fishing year. 

– https://gulfjournal.org.nz/wp-content/uploads/2020/02/State-of-our-Gulf-2020.pdf

Recreational catch in the HPAs for the 2017/18 fishing year = 248 + 18% (45) = 293 tonnes. 

Calculating the weight of commercial catch lost to trawl corridors

Option 1 would result in an estimated reduction in landings of approximately 632 tonnes of fish per year. Option 4 would result in an estimated reduction in landings of approximately 1017 tonnes of fish per year.

Submissions on the protections proposed by Revitalising the Gulf

I spent a few days going through the 7,550 submissions on protections proposed by Revitalising the Gulf. I’m estimating 77%-90% of the submissions were positive about the protection proposals. However huge numbers concerned about the continuation of bottom impact fishing outside the protected areas and cultural take inside them. So there is a general need for more protection. This level of public support for marine protection can be expected and can be seen in Polling from the Hauraki Gulf Form, Submissions on the recent Waiheke Marine Reserve Proposal and the Live Ocean Barometer 2023.

Most of the names were redacted from the submissions but the organisation names were left public. Here are the names of the organisations that made significant submissions.

Most of these submitters were upset about continued bottom impact fishing in the Gulf. Most of the Charter fishers all sent in the same submission. These submitters indicated support for marine protection but did not express that much support for the proposed measures: Most of these submitters wanted more protection than what was proposed and also wanted bottom impact fishing banned.

I have not published the names of many organisations who used the LegaSea form as those submissions contained dramatically less information than those from the above organisations. They were mostly small owner operator companies who are also keen fishers. The big Purse Sein operator Pelco NZ Ltd and Te Ahu wai o Tangaroa sustainable ecological aquaculture did make significant submissions but they did not speak to the protection proposal.

In response to the submissions the Department of Conservation has reduced the amount of protection. Submissions are now open on the Hauraki Gulf / Tīkapa Moana Marine Protection Bill.

P.S. These bottom impact fishing effort maps were made public by Fisheries Inshore NZ and are useful in considering the proposed ‘trawl corridoors’.

Submissions on the Hauraki Gulf Fisheries Management Plan

Over 10,000 submissions on the Hauraki Gulf Fisheries Management Plan are likely to be the largest data set of opinions on fisheries management in Aotearoa and definitely the largest in the Hauraki Gulf Marine Park.

This copy is displayed when asking for public submissions:


Submissions are public information
Note that all, part, or a summary of your submission may be published on this website. Most often this happens when we issue a document that reviews the submissions received.

People can also ask for copies of submissions under the Official Information Act 1982 (OIA). The OIA says we must make the content of submissions available unless we have good reason for withholding it. Those reasons are detailed in sections 6 and 9 of the OIA.

If you think there are grounds to withhold specific information from publication, make this clear in your submission or contact us. Reasons may include that it discloses commercially sensitive or personal information. However, any decision MPI makes to withhold details can be reviewed by the Ombudsman, who may direct us to release it.


I’m disappointed that Fisheries New Zealand has not released all the submissions citing section 18(f) of the OIA—that the information requested cannot be made available without substantial collation or research.

I’m going to read over the submissions provided (which are substantial) before asking for more detail.
