I asked ECAN Metro to sign the CC-BY waiver for their GTFS data, they declined.

Kia Ora Eliot,
Thank you for your email. Environment Canterbury is unable to sign the permission form below. There are multiple users of the Metro GTFS data and Environment Canterbury wishes to have the same terms applying to each user, as provided for in Creative Commons CC BY 4.0 licence, and not have individual user variation to those terms.
While this email does not constitute legal advice on OpenStreetMap’s obligations under the Creative Commons CC BY 4.0 licence :
1 For the purposes of Section 3(a) of the Creative Commons CC BY 4.0 licence, the manner of attribution you describe below is probably sufficient to satisfy the attribution requirements.
2 In relation to Section 2(a)(5)(B), the downstream restrictions you refer to are not likely to be a common occurrence.
Noho Ora Mai,
Matthew

Dear Metro,
Thank you for making Metro’s GTFS data (Developer resources | Metro Christchurch) available under the Creative Commons CC BY 4.0 license.
I am a volunteer for OpenStreetMap, a collaborative open project to create a global geodata set freely usable by anyone on share-alike and attribution terms under the Open Database License (ODbL). In fact you already use OpenStreetMap map data on go.metroinfo.co.nz (Copyright | Metro Christchurch)
We’re interested in using the Metro’s GTFS data to improve OpenStreetMap, by keeping the bus route and stop information in the map up to date and consistent with Metro. This would happen using a combination of manual and automated comparison between your current data and the OSM map data.
In order to facilitate this, we need to confirm with you that Metro has no objections.
Your use of CC-BY-4.0 indicates that you intend for the data to be used freely, but there are two issues we would like to clarify.
First, because OpenStreetMap’s data comes from thousands of local volunteers as well as numerous government sources, attribution to all such sources on an OpenStreetMap-based map or similar visual display is impossible. Instead, we provide attribution (including original license information) to major sources like Metro on our Contributors page. OpenStreetMap users are then required to attribute “OpenStreetMap Contributors” in a collective fashion when using any OpenStreetMap data. CC BY’s attribution requirements are relatively general, so we just need you to confirm that you would consider OpenStreetMap’s attribution method to attribute Metro in a “reasonable manner” in accordance with Section 3(a)(1) of the CC BY 4.0 license.
You can see examples of other New Zealand entities that have given similar permission here Contributors - OpenStreetMap Wiki
Second, the ODbL and CC BY 4.0 have slightly different ways of addressing digital rights management technologies. The ODbL allows data users to apply technical protection measures to their own works so long as they also provide an unrestricted version of the underlying database, including their own additions (“parallel distribution”). In contrast, CC BY 4.0 can be read to prohibit any application of technical protection measures to databases that include CC BY material. This is a relatively minor difference in how the licenses are drafted, but means that in some cases, users who comply with ODbL might not comply with CC BY 4.0.
In practice, we have found that parallel distribution is an excellent way of ensuring open access to data while allowing flexibility in use. Thus, we ask that, to the extent CC BY 4.0 Section 2(a)(5)(B) prohibits any downstream restrictions even when parallel distribution is available, you waive this license restriction as to OSM and its users. This waiver would have no effect on [entity’s] original dataset and only pertains to the restrictions allowed on combinations of that data with OSM data.
Thank you for your consideration. If Metro is amenable, can you please check the form below and return a signed version to me?
If you have any questions or would like more information about OpenStreetMap, please do not hesitate to contact me by phone or e-mail.
Thanks and regards,
Eliot Blennerhassett
