This included the impact on people with existing water-take consents who wanted to renew them.
"The intent all along has been to not impact on the ability of existing consent holders to obtain new consents on similar terms, on the expiry of existing consents," the memorandum said.
"This applies whether the new consent is effectively replacing like for like, or whether it is a 'global' consent that replaces a whole set of consents."
Where existing takes were subject to minimum flow cut-off, the replacement consents could be granted subject to that same minimum flow, with the regional council through its regional plan and consent process able to determine whether a higher minimum flow should apply.
The allocation limit would not impact existing consents, the memorandum iterated.
"As with the previous draft WCO, the second draft is not permitting such takes, it is simply not prohibiting them. That remains the role of the HBRC to decide on the merits of any application and whether further consents should be granted, and whether that should be on similar terms to the expired consent," the revised draft order said.
The second draft still included environmental bottom lines for the granting of consents for entirely new takes, as was the case with the first draft.
In addition, the memorandum said new evidence for the Department of Conservation had identified the outstanding values of the Kaweka Lakes, and these had now been specifically identified as waters to be retained in a natural state.
In terms of water quality standards for the upper Ngaruroro River, there had also been some amendments to water quality limits, and a number of those had been amended from annual to five-year median limits.
It was expected that before the Stage 2 hearings began a third draft would be compiled taking into account the TANK science and scenario modelling, any TANK recommendations, and any discussion with submitters.
The memorandum said it was standard practice for draft WCOs to be revised through the course of a hearing to respond to matters raised.
On the final day of the first stage hearings last month, tribunal chairman Richard Fowler said the reconvening date for Stage 2 had been delayed from May to July.
He said the break between the stages was "an excellent opportunity" for all involved to collaborate to reach common ground.
